1. General

(1.1) Since this part is based on a fast-track DTR submitted from Japan, we request that this part be freely available.

2. Technical

(2.1) The combination of XML 1.1 and Namespaces 1.1 should be allowed.

(2.2) It should be possible to create multiple element sections from a single-namespace document. This allows the use of NVDL for large single-namespace vocabularies (e.g., DocBook or CALS). We propose to introduce <trigger> elements as children of the <rules> element.

    <rules>
      <trigger ns="..." name="...."/>
      <trigger ns="..." name="...."/>
        ...
      <mode...>
        ...
      </mode>
      ...
    </rules>

(2.3) Improve "mode inclusion" on the basis of multiple inheritance in programming languages.

(2.4) Introduce schema rewriting for those RELAX NG schemas which are referenced from validate actions applied to attribute sections.

(2.5) The semantics of path expression matching should be clearly defined.

(2.6) Introduce the dummy and root-only option.

(2.7) Register a media type for the RELAX NG compact syntax at IANA and mention it in this standard.

3. Editorial

(3.1) Section 7.7 (invoking non-NVDL validators) should be deleted, since we already have Section 8.7.

(3.2) In 6.4.12 (mode inclusion), clearly state that the use of XInclude or parsed entities is intended for syntactical inclusion and that "mode inclusion" provides post-processing after syntactical inclusion.

(3.3) In Section 8, a new subsection is needed for explaining the creation of sections from instances. This section should refer to 5.2.

(3.4) Options have problems as below:

It is impossible for this part to specify options for all schema languages,
Different implementations of one schema language may provide different options, and
The syntax of options might be more complicated than name-value pairs. To overcome these problems, we propose to make the syntax and semantics of options entirely implementation-dependent.
