Additional U.S. Comments on SC34/N007

1. Previous US comments recommended an XML-conformant version of the

ISMID architecture and noted in particular the implications for the

start- and end-tag omission parameters of element type declarations.

Note that the XML version is subject to other restrictions. One

example is the use of SGML comments as separators in declarations

other than comment declarations. While we had recommended following

the style developed for ISO/IEC 10744:1997 in element type and

attribute definition list declarations, this style calls for comments

between the parameters of these declarations. Since such comments

are not permitted in XML, the XML version of the architecture must

place comments describing the element types and attributes outside of

the declarations.

2. In the name of the Standard and the language, change "Modifiable"

to "Multimedia". We make this request because the term "modifiable" is

not generally used in conjunction with interactive documents, while

such documents are almost invariably used in multimedia applications.

3. ISO 8879 does not define (or even use) the term "valid SGML

document". The correct phrase is "conforming SGML document".

4. Definitions that come from other standards should identify their

source (e.g. "document" is from 8879).

5. Add (or revise as indicated) the following definitions. Change the

text as needed to use these terms consistently (e.g., distinguish

appropriately between "interactive document" and "interactive

presentation").

interactive presentation

A form of presentation of a document in which the order of navigation

through the document content is modified during presentation in

response to conditions.

NOTE: The modifications are typically in response to external stimuli,

such as user interactions, which is why these presentations are termed

"interactive". However, the dynamic modification can also be in

response to presentation algorithms contained in the document or

within the system controlling the presentation.

NOTE xx. A document need not be an interactive document in order for

it to be the subject of an interactive presentation.

interactive document

A document that is not intended for static presentation. It typically

contains algorithms for its own interactive presentation.

static presentation

A form of presentation of a document in which the order of navigation

through the document content is essentially the same as the order in

which the content appears in the computer representation of the

document.

NOTE xx. In a static presentation, any dynamic modification is

typically limited to the navigational functionality offered by a

printed volume, such as page-turning and cross-reference following.

static document

A document that is intended for static presentation.
