Renumber the notes in the corrected Annex K with a sequence of integers, beginning with "1". (In this TC the notes are numbered sequentially within this document, with the numbers prefixed with "R".)
Replace second paragraph of K.1 with:
This annex is organized as a set of replacement and new syntax productions and text, and is phrased in terms of modifications to be made to the body of this International Standard, though the numbers of the affected clauses are not necessarily cited. However, these modifications are applicable only when conforming to this annex.
Replace text of K.2.1.2 with:
The portion of a document type declaration subset located within the external subset entity.
Add new clause:
K.2.1.4 external subset entity:
The entity that is declared by the external identifier parameter of a document type declaration and referenced (implicitly) at the end of the internal subset.
Replace title and text of K.2.2 with:
K.2.2 Definitions related to document instances
K.2.2.1 fully-declared document instance:
A document instance whose associated document type declaration contains sufficient markup declarations to express all of the DTD properties required for the instance by the body of this International Standard, and that does not contain DTD data entities that modify those properties.
The document type declaration itself could be an implied declaration, as provided in clause K.4.9.
Note R1: An SGML declaration requires document instances to be fully-declared if it specifies IMPLYDEF ATTLIST NO and ELEMENT NO ENTITY NO NOTATION NO. A system should offer means, such as a parameter to the invocation of processing, to request validation of whether an instance is fully-declared even when the SGML declaration does not require it to be.
A document instance that is not fully-declared must be either a fully-tagged document instance or an amply-tagged document instance.
K.2.2.2 fully-tagged document instance:
A document instance in which a start-tag with a generic identifier, and an end-tag, are present for every element, and the attribute name is present in every attribute specification in the start-tag.
Note R2: An SGML declaration requires document instances to be fully-tagged if it specifies DATATAG NO, RANK NO, OMITTAG NO, SHORTTAG STARTTAG EMPTY NO, and SHORTTAG ATTRIB OMITNAME NO. A system should offer means, such as a parameter to the invocation of processing, to request validation of whether an instance is fully-tagged even when the SGML declaration does not require it to be.
K.2.2.3 type-valid document instance:
A document instance that conforms to such DTD properties as are required for it by the body of this International Standard and that are expressed in its associated document type declaration, either by markup declarations, DTD data entities, or both.
K.2.2.4 amply-tagged document instance:
A document instance whose use of markup minimization does not require access to a document type declaration.
Note R3: An SGML declaration requires document instances to be amply-tagged, insofar as they use minimization, if it specifies DATATAG NO, RANK NO, SHORTTAG ATTRIB OMITNAME NO, and either IMPLYDEF ELEMENT NO or IMPLYDEF ELEMENT ANYOTHER. A system should offer means, such as a parameter to the invocation of processing, to request validation of whether an instance is amply-tagged even when the SGML declaration does not require it to be.
Note R4:
End-tags can be omitted in an amply-tagged document instance, even for element types that have been declared by default as provided for in K.3.7.
More precisely, an amply-tagged document instance can omit the end-tag for an element of an implicitly-declared type by satisfying any of the three conditions -- a), b), or c) -- specified in 7.3.1.2. However, condition c) can be satisfied only when "IMPLYDEF ELEMENT ANYOTHER" is specified in the SGML declaration and the element is followed by another element of the same type.
The following amply-tagged document instance illustrates these possibilities when "IMPLYDEF ELEMENT ANYOTHER" has been specified and there are no DTD declarations:
<chapter> <title>Chapter title</title> <list> <item>First item in the list <item>Second item in the list </list>The end-tag for the first item in the list can be omitted because of condition c): This element is followed by an element that is not allowed in its content--in particular, another item.
The end-tag for the second item in the list can be omitted because of condition b): This element is followed by the end-tag of another open element (the list).
The end-tag for the chapter can be omitted because of condition a): This element is followed by the end of the SGML document entity.
K.2.2.5 immediately recursive element:
An element whose immediate content includes a child subelement of the same type.
Note R5: In the following fully-tagged text, the first section element is immediately recursive while the first list element is not.
<section> <title>The title</title> <section> <p>The data.</p> </section> </section> <list> <item>First outer list item</item> <item>Second outer list item, which contains an inner list. <list> <item>Inner list item</item> </list> </item> </list>Note R6: A system should offer means, such as a parameter to the invocation of processing, to request validation that an an instance contains no immediately recursive elements even when the DTD would permit them.
Add new clause:
K.2.5 Definitions related to DTD notations
K.2.5.1 DTD notation:
A data notation that is capable of expressing DTD properties.
Note R7: This International Standard provides markup declarations as the means of expressing DTD properties. It also allows the use of DTD notations, but does not define any.
Note R8: A DTD notation can also be capable of expressing other information. For example, it could express constraints on a document's data content or structure that cannot be expressed by markup declarations but could be validated by an application. However, it is not an SGML error if the document fails to conform to such additional constraints.
Note R9: DTD notations are used in DTD data entities.
K.2.5.2 DTD properties:
Classes and properties that are specifiable by markup declarations. They are defined by the following grove plan:
<!DOCTYPE grovplan PUBLIC "ISO/IEC 10744:1997//DTD Grove Plan//EN"> <grovplan propset=SGMLProp id=dtdprops> <title>DTD Properties Grove Plan</title> <desc> Classes and properties that are specifiable by DTD declarations. They are needed to parse and validate a document instance. </desc> <inclmod> prlgabs0 prlgabs1 dtgabs rankabs srabs subdcabs fpiabs arcabs fsiabs dafeabs gadcabs pelement </inclmod> <inclclas> sgmldoc doctpdcl </inclclas> <omitprop classes="sgmldoc"> appinfo epilog </omitprop> </grovplan>K.2.5.3 Parameter entity (4.225)
An entity that is either the external subset entity, or that is declared with a parameter entity name.
K.2.5.4 DTD data entity:
An external parameter entity whose declaration includes a notation name.
Note R10: The notation name should be that of a DTD notation and the entity content should describe DTD properties.
Replace the paragraph after production [171.2] with:
An external identifier, if it is a formal public identifier, should use "SD" as the public text class to identify an SGML declaration body, rather than one of those listed in 10.2.2.1.
In 10.2.2.1 replace the phrase "The name must be" with "The name should be".
Change the title of K.3.2 to "SGML declaration body".
Replace Note 11 with the following:
Certain parameters of the SGML declaration body are omissible in order to allow documents to declare conformance to this annex by a simple change to the minimum data. An omitted parameter has no effect on the document; that is, with respect to the subject of the omitted parameter, the document is the same as if it did not conform to this annex.
Note R11: Nevertheless, it is recommended that all parameters be specified.
Replace the text of K.3.5 with:
[196] markup minimization features = "MINIMIZE", ps+, "DATATAG", ps+, ("NO"|"YES"), ps+, "OMITTAG", ps+, ("NO"|"YES"), ps+, "RANK", ps+, ("NO"|"YES"), ps+, "SHORTTAG", ps+, ("NO"|"YES"| (start-tag options, ps+, end-tag options, ps+, attribute-options)), (ps+, empty element ending rules, ps+, implied default declarations)?Note R12: Use of an enabled markup minimization feature may be affected by the operation of other provisions of this International Standard, including other markup minimization features.
K.3.5.1 SHORTTAG start-tag options
[196.1] start-tag options = "STARTTAG", ps+, "EMPTY", ps+, ("NO"|"YES"), ps+, "UNCLOSED", ps+, ("NO"|"YES"), ps+, "NETENABL", ps+, ("NO"|"ALL"|"IMMEDNET") where EMPTY YES enables empty start-tags. UNCLOSED YES enables unclosed start-tags. NETENABL ALL permits NET-enabling start-tags and null end-tags; and IMMEDNET restricts them to elements with empty syntactic content that must be ended by a NET, so it cannot be specified if EMPTYNRM NO is specified.Note R13: An element with empty syntactic content need not have been declared EMPTY.
K.3.5.2 SHORTTAG end-tag options
[196.2] end-tag options = "ENDTAG", ps+, "EMPTY", ps+, ("NO"|"YES"), ps+, "UNCLOSED", ps+, ("NO"|"YES") where EMPTY YES enables empty end-tags. UNCLOSED YES enables unclosed end-tags.K.3.5.3 SHORTTAG attribute options
[196.3] attribute options = "ATTRIB", ps+, "DEFAULT", ps+, ("NO"|"YES"), ps+, "OMITNAME", ps+, ("NO"|"YES"), ps+, "VALUE", ps+, ("NO"|"YES") where DEFAULT YES enables attribute value defaulting (7.9.1.1). OMITNAME YES allows attribute names and vi to be omitted for unique NMTOKEN values (7.9.1.2). VALUE YES allows some attribute values to be specified without delimiters, rather than as literals (7.9.3.1).Note R14: DEFAULT NO does not bar default values from attribute definition list declarations.
Replace text of K.3.6 with:
[196.4] empty element ending rules = "EMPTYNRM", ps+, ("NO"|"YES") where EMPTYNRM YES applies normal rules for the presence of end-tags, including markup minimization rules, to elements of a type declared EMPTY, or that are forced to be EMPTY by an explicit content reference attribute (7.3.).Note R15: Specifying EMPTYNRM YES applies to mandatorily empty elements the same rules about the presence of end-tags that apply to other kinds of elements.
Replace title and text of K.3.7 with:
K.3.7 Implied default declarations
[196.5] implied default declarations = "IMPLYDEF", ps+, "ATTLIST", ps+, ("NO"|"YES"), ps+, "DOCTYPE", ps+, ("NO"|"YES"), ps+, "ELEMENT", ps+, ("NO"|"YES"|"ANYOTHER"), ps+, "ENTITY", ps+, ("NO"|"YES"), ps+, "NOTATION", ps+, ("NO"|"YES") where DOCTYPE YES means that an implied document type declaration includes an implied declaration for an external subset entity (see K.4.9); and YES for the other parameters allows information of the specified type to be used in a fully-tagged or amply-tagged document instance without an explicit declaration. Instead, a declaration is implied, as follows: ATTLIST YES means an undeclared attribute is declared as: CDATA #IMPLIED ELEMENT YES means an undeclared element type is declared as: - O ANY ELEMENT ANYOTHER means an undeclared element type is declared as: - O ANY but immediately recursive elements of that type are prohibited. ENTITY YES means an undeclared general entity is declared as: SYSTEM NOTATION YES means an undeclared notation is declared as: SYSTEMWhen IMPLYDEF ELEMENT ANYOTHER and OMITTAG YES are specified, the end-tag of an element of an undeclared type can be omitted from an amply-tagged instance when the element is followed by the start of an element of the same type.
Note R13: IMPLYDEF DOCTYPE YES implies only a declaration for an external subset entity. Other declarations may be implied if needed, and if permitted by the applicable IMPLYDEF parameters.
When IMPLYDEF ENTITY YES is specified, #DEFAULT cannot be specified as a general entity name.
Implicitly declared definitions occur in the grove in the order in which it is necessary to imply their declarations. No attribute assignment node is created for an attribute unless the attribute is specified.
Note R16: An implied declaration is not necessarily the same as an explicit declaration for the same object that was ignored during parsing (Note R24). Nor does it constrain any explicit declaration that might be created for that object as a result of processing (for example, when generating an explicit DTD for a document that has none).
Replace text of K.3.8 with:
[198] other features = "OTHER", ps+, "CONCUR", ps+, ("NO"|("YES", ps+, number)), ps+, "SUBDOC", ps+, ("NO"|("YES", ps+, number)), ps+, "FORMAL", ps+, ("NO"|"YES"), (urn feature, keeprsre feature, validity feature, entities feature)?K.3.8.1 Universal Resource Names
[198.1] urn feature = ps+, "URN", ps+, ("NO"|"YES") where URN YES means public identifiers are interpreted according to the applicable Internet Engineering Task Force RFC2141 governing Universal Resource Names.If both URN and FORMAL are YES, public identifiers are interpreted either as formal public identifiers or as URNs.
K.3.8.2 White space in content
[198.2] keeprsre feature = ps+, "KEEPRSRE", ps+, ("YES"|"NO") where KEEPRSRE YES means clause 7.6.1 does not apply.Note R17: If KEEPRSRE YES is specified, all white space in mixed content is included in the grove as datachar nodes.
Note R18: This option does not affect delimited strings, such as attribute value literals, which have their own rules for normalizing white space (and which, in any case, do not occur in content).
K.3.8.3 Assertions
[198.3] validity feature = ps+, "VALIDITY", ps+, ("NOASSERT"|"TYPE") where NOASSERT makes no validity assertion. TYPE asserts that document instances are type-valid. If the parameter is omitted, TYPE is assumed. [198.4] entities feature = ps+, "ENTITIES", ps+, ("NOASSERT"| ("REF", ps+, ("NONE"|"INTERNAL"|"ANY"), ps+, "INTEGRAL", ps+, ("NO"|"YES"))) where NOASSERT makes no validity assertion. REF asserts the document either has unconstrained entity references (ANY), is external-reference-free (INTERNAL), or is reference-free (NONE). INTEGRAL YES asserts document instances are integrally-stored. If the parameter is omitted, NOASSERT is assumed.It is a reportable markup error if a document is less constrained than is asserted.
Note R19: For example, if an otherwise conforming document incorrectly asserts that it is integrally-stored, the document is non-conforming. Had the assertion not been made, the document would have been conforming.
Note R20: A system should offer means, such as a parameter to the invocation of processing, to check whether a particular VALIDITY or ENTITIES assertion could correctly be made for a document, even when the SGML declaration does not make that assertion.
Note R21: To satisfy the classical requirement for SGML conformance, a document instance must be fully-declared as well as type-valid.
Replace last sentence with:
However, a definition associated with ALL can be overridden by subsequent attribute declarations for specific element types or notations (including declarations specified with IMPLICIT), except when the attribute has already been specified. It is therefore an error to specify a data attribute that was declared with ALL and then to attempt to redeclare that attribute.
Replace title and text of K.4.4.2 with:
K.4.4.2 Declared value
[145] declared value = "CDATA"|"ENTITY"|"ENTITIES"|"ID"|"IDREF"|"IDREFS"|"NAME"|"NAMES"| "NMTOKEN"|"NMTOKENS"|"NUMBER"|"NUMBERS"|"NUTOKEN"|"NUTOKENS"| notation|name token group|data specificationReplace the penultimate paragraph of 11.3.3 with:
A token can occur more than once in an attribute definition list provided that each occurrence of the token is in the name token group or name group of a different attribute definition. In an attribute specification where the value is such a duplicated token, omitted attribute name minimization cannot be used.
K.4.4.3 Data specification
[145.1] data specification = "DATA", ps+, notation name, data attribute specification? where: "notation name" identifies the data content notation of the attribute's value "data attribute specification" specifies the corresponding data attributesThe value of an attribute whose declared value is "data specification" is character data.
Note R22: An application may wish to verify that the value of a data specification attribute is meaningful in light of the specified notation name and data attributes, but it is not an SGML error if this is not the case.
Replace text of K.4.5 with:
[111] document type name = (generic identifier | (rni, "IMPLIED")) where IMPLIED means the document element can have any valid element type name.It is a reportable markup error if IMPLIED is specified and the start-tag of the document element is omitted or does not contain a generic identifier.
IMPLIED cannot be specified if LINK EXPLICIT YES or CONCUR YES are specified in the SGML declaration.
Change production number [2] to [3].
Replace title and text of K.4.9 with:
K.4.9 Omitted prolog (7.1)
If LINK EXPLICIT NO and CONCUR NO are specified in the SGML declaration and either or both of IMPLYDEF DOCTYPE YES or IMPLYDEF ELEMENT YES are specified, and if the document instance is either fully-tagged or amply-tagged, the SGML document entity need not contain a prolog. In such cases, a prolog will be implied consisting solely of a single implied document type declaration, as follows:
- If IMPLYDEF DOCTYPE YES is specified:
<!DOCTYPE #IMPLIED SYSTEM []>- If IMPLYDEF DOCTYPE NO is specified:
<!DOCTYPE #IMPLIED []>Note R23: When both the document type name and the external subset entity are implied in a document type declaration, a system may be able to locate an appropriate external subset by considering the storage identifier of the SGML document entity and/or the generic identifier of the document element.
If permitted by the implied default declarations parameter of the SGML declaration, a document type declaration (whether explicit or implied) may lack declarations for element types, attributes, notations, and/or general entities. Declarations are implied for them as provided in K.3.7.
Note R24: If some or all of an instance's associated document type declaration should be unavailable or for other reasons ignored during parsing, then:
- It is recommended that the constructed grove be the same as if implied declarations had replaced the ignored ones; and
- Whether or not the instance is fully-declared, the constructed grove could well differ from the grove that would be constructed by a conforming SGML parser that processes all the declarations that are present.
Add new clause:
K.4.10 DTD data entities
K.4.10.1 DTD notations
To the extent that an SGML system can recognize properties expressed by DTD notations, it shall treat them identically to DTD properties that are expressed by markup declarations.
It is a reportable markup error if a DTD data entity is referenced and its representation of required DTD properties is not understood by the system and it is not permissible to imply default declarations for them.
Note R25: Therefore, when implied default declarations are permitted, the use of a DTD notation that cannot be understood has the same effect as omitting the equivalent markup declarations.
K.4.10.2 External parameter entity declaration (10.5.5)
An entity declaration for an external parameter entity can include an entity type that specifies the name of a data notation.
K.4.10.3 External subset entity
Production 110 is replaced with:
[110] document type declaration = mdo, "DOCTYPE", ps+, document type name, (ps+, external identifier, (ps+, ("CDATA"|"NDATA"|"SDATA"), ps+, notation name)?)?, (ps+, dso, document type declaration subset, dsc)?, ps*, mdcThe notation name must be declared within the internal subset of the document type declaration.
Note R26: If data attributes are to be specified for a DTD data entity, the entity must be declared by an entity declaration; that is, the entity cannot be the external subset entity.
Add new clause:
K.4.11 Content model (11.2.4, 11.2.5)
[129] primitive content token = ( rni , ("PCDATA" | "ALL" | "IMPLICIT")) | element token | data tag group where ALL and IMPLICIT have the same meaning as in K.4.4 and are equivalent to optional repeatable OR groups.#ALL and #IMPLICIT are allowed in the name groups in [139] and [140]. They have the same meaning as in K.4.4.
Replace title and introductory text of Annex L with:
Annex L (informative): Added Requirements for XML
This annex illustrates the relationship of SGML declarations to "added requirements" by means of a real-world example, XML. It is not intended as a specification for XML.
Replace first paragraph of L.1 with:
The Extensible Markup Language (XML) is the core subset of SGML functionality developed by the World Wide Web Consortium (W3C) for exchanging SGML documents over the World Wide Web. The current specification for XML can be found at the W3C web site at "http://www.w3.org/TR/" under the title "Extensible Markup Language (XML)".
Replace the unordered list in L.1 with:
- An XML document must be "well-formed" by XML rules: it is a conforming SGML document whose document instance is fully-tagged and integrally-stored.
- A well-formed XML document may also be "valid" by XML rules: its document instance is also type-valid and fully-declared.
