Now I don't understand your position any more:

Surely parsed entity declarations are part of the document.  How can you
allow parsed entity declarations but disallow the XML version number
without exhaustively enumerating all the things in the document that you
are going to allow access to? And I certainly don't want to do that.

Incidentally, I think accessing the version number is perfectly
reasonable.  Suppose the set of name characters changes in some future
version of XML.  Why shouldn't a datatype library have a datatype that
accepts a NCName, where what a NCName is depends on the XML document it
occurs in?
