The original question was, when the subject XML was tried in IE5 and
produced an error,

"Why is this error appearing and what can be done to solve it "

The "Why" is a combination of my response and IE5 quirks.  You can't equate
what the parser in IE5 does with complete compliance with the standard.

I'll go along with that.

My version of IE5 does not need to have the namespace declared as a #FIXED
attribute - it doesn't need it to be declared as an attribute at all.  It
doesn't mind if it is declared, though.
