Re: [xml-dev] Default namespace declaration in DTD and MSXML

["Wayne Steele" <xmlmaster@hotmail.com>]

Either way is valid, acceptable, conformant, and non-deprecated.

As you have discovered, the MSXML parser does not tolerate the xmlns 
attribute being defaulted via the DTD. This is either a bug, or a limitation 
of this parser, depending on how charitable you're feeling.
