I can't buy this.  The W3C specifications for XML and for namespaces are
quite settled ... and _neither_ one places a requirement that declared
"xmlns*" attributes must have "#FIXED" default values.

In fact, the statements that exist make it clear that from the XML 1.0
syntax point of view, "xmlns*" are like other attributes ... which may
be defaulted or not, and hence may omit (or include) "#FIXED" depending
on what a given DTD author chooses to do.

Sound like you're saying it's conservative to treat MSXML as the holder
of the standards, rather than the W3C documents.  That's not a very
popular attitude outside of Redmond!

In a standards context, "conservative" means implementing only (and
exactly!) what the specifications say.  I don't think this is what
Microsoft has done in this case.   Speculating on the reasons why may
be amusing, but I'd rather see this bug fixed (soon!) instead.
