Hmm and what about Element, Attribute and even Entity declarations within an 
external subset DTD? (i've got in mind the pizza model of the TEI DTD). The 
XML REC says that "If the same entity is declared more than once, the first 
declaration encountered is binding;" (4.2 Entity Declarations). Why can't we 
make the same kind of binding for NS prefixes ?

I fully agree with you:

	"An XML document is an XML document !"

I quote Lou Burnard who used to say that "an SGML document is an SGML 
document" talking about entities and document fragments in SGML.

A Bientôt !
