Re: Question about WXS datatypes ID, IDREF and IDREFS

[Kohsuke Kawaguchi <Kohsuke.Kawaguchi@Sun.COM>]

The DTD compatibility spec does not define its own ID datatypes. IOW,
there's no such thing as "DTD ID type".
It simply defines the "ID-ness" that can be assigned to datatypes.

This is true. Some instances could be considered valid by a RNG processor
without DTD compatibility support, and the same documents could be
considered invalid by a RNG processor with DTD comp. support.


I believe one option we've considered is to add something like SOAP's
@mustUnderstood so that the schema can say "I want to require this
particular extension (like DTD compatibility) for this schema"
