Dawns on me that the real issue here is probably that IE5
doesn't let you browse DTD files directly.  Reasonable, and
if so, not at all a bug.

As David noted, (different words) they may be XML, but they're
not documents and when you try to view an XML "file" the browser
must assume it's a document.  Ergo the diagnostic.  If the
text declaration looked like an XML declaration (with version)
you'd get an error because the first declaration was for an
element or somesuch, rather than a document!

p.s. XMLNews ... cool stuff!  I'll look at it in more detail soon.
