Quick note:

    If we do mandate that the GRDDL spec should exercise XInclude and
reflect any declared DTD or Schema, we do make the implementation
slightly harder.  In essence, we restrict any GRDDL implementers to use
XML parsers and libraries, in particular those that implement XInclude
(for example, while 4Suite by default in the parse resolves XIncludes,
while Xalan of course can resolve XIncludes but requires it to be made
explicit).  While that's fairly easy, I'm thinking default attributes
via XML Schema may be harder (although of course not impossible) for
implementers. Any opinions?
