Hmm and what about Element, Attribute and even Entity declarations within=

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 Bient=F4t !
