2) The notion of "document type" should be brought back, as representing
something different from a namespace.  A namespace is a vocabulary,
a schema is rules for using that vocabulary, a document type is a combination
of schemas combined with house-rules, business-rules, characteristic
styles, expected usages, _emantics, allowed roots, comment conventions,
PI conventions, constraints not expressible with schema languages, 
localizations, characteristic file extensions, MIME type, controlled
vocabularies, and so on.
