The review period lasts until Sunday, 25 October and covers sections 4 and 5, appendix C, and those parts of sections 1-3 that have changed since the last version.  (The rest of sections 1-3 are frozen.)

If no technical questions are raised, the spec will be considered final on Monday, 26 Oct.

-- Ron Bourret


Changes since 23 Sept draft:

* Added ElementNS attribute to XSchema, Mixed, Choice, Seq, Ref, AttGroup, and AttDef.  ElementNS is needed to refer to elements in a two-part (namespace, name) naming system.

* Removed Model from the content model of Model.  (It is still allowed in Choice and Seq.)

* Clarified the description of Mixed.

* Created Enumeration element and added to the content models of AttDef and XSchema.

* Rewrote 2.4.0 (Attribute Declarations) to clean up existing material and incorporate ElementNS attribute.

* Added Doc and More to content model of UnparsedEntity.

* Added information to section 3.0 about how to construct XSchema documents that can be used in both namespace-aware and -unaware environments.

* Rewrote section 3.2 (Namespaces of Elements and Attributes Being Defined) to incorporate ElementNS attribute.

* In section 4.1 (DTDs in XSchema Documents), stated that, if an XSchema document includes a DTD, the doctype must be XSchema and any user-specific markup declarations cannot override anything in the XSchema DTD.

* In section 4.3 (Converting Between XSchema Documents and DTDs), stated that converters can generate comments at will.

* PIs are discarded when converting from DTDs to XSchema documents.

* Added public identifier to XSchema PI, made system identifier mandatory, and fixed names and capitalization.

* Mentioned FileExtension attribute in section 5.2.7 (Authoring).

* Added Appendix C (XSchema in XSchema).
