[x3d-public] announce: X3D XML schema/DTD updates - name attribute not required if USE node is possible

[Don Brutzman]

X3D XML Schema/DTD updates:

29 May 2017 brutzman walmsley
- name attribute not required for Metadata* and *VertexAttribute (v3.1+) nodes,
   since cannot REQUIRE @name field or else USE nodes fail to validate
- changed *VertexAttribute name fields to NMTOKEN for stricter name checks


For Web3D members, these changes are typically examined and resolved in the Mantis issue tracker.

     Mantis issue 1092
     Core component - MetadataSet or Metadata* node(s) as root nodes
     http://www.web3d.org/member-only/mantis/view.php?id=1092

Tooltips updated to match.

     http://www.web3d.org/x3d/content/X3dTooltips.html

Corresponding X3DJSAIL improvements: name requirements and strict typing checks are included in validation() method for each node.

     http://www.web3d.org/specifications/java/X3DJSAIL.html

These updates are checked with latest version of Java jdk1.8.0_131 and documentation generated using recent release of XMLSpy.  Looking good.  Schema/DTD bugfixes and documentation are now published and deployed, references follow.  No changes to existing X3D scene content are needed.

TODO: corresponding JSON Schema updates, following the Web3D 2017 Conference.

Thanks for all ongoing reports and suggestions.  Have fun with high-quality X3D!  8)

X3D Schema assets can be found on the X3D Specifications: XML Schema and DOCTYPE Validation page.

           http://www.web3d.org/specifications

Full documentation updates have been autogenerated for the XML Schema and DOCTYPE, available for X3D versions 3.0 through 3.3 plus experimental 4.0.  Recommended X3D version is 3.3.

X3D Schematron Validation and Quality Assurance (QA) rules are also regularly updated in concert with these changes.

       http://www.web3d.org/x3d/tools/schematron/X3dSchematron.html

The X3D Working Group also maintains the X3D Graphics Standards: Specification Relationships diagram up to date, showing the roadmap for all major planned work.

Please note that X3D version 4.0 Schema and DTD are experimental and support specification development.

All versions of these assets are maintained under open-source version control at

       https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/specifications

Changes are tested through validation regression testing of 3800+ open-source X3D scenes.
