Sorry. If you were trying to pre-empt more debate ... too late, I've
sent it off!

I'm sure that raised a few smiles!
As it happens, your approach is worse than useless. If in the future the
value of 'xmlns' is actually part of determining whether a document is
valid or not, then so be it. DTDs will need to change. But that also
goes for XLink, fragments, XML-Data and more. The fact is that as far as
I can tell, at the moment there is nothing in XML 1.0 or the namespace
spec that says the value of a namespace MUST be fixed. Yet because
Microsoft have decided they should be - and many may agree - I am now
unable to get perfectly valid DTDs, over which I have no control, past
your parser. This is not conservative ... it is WRONG.
What really amazes me is why you have picked this feature to be
restrictive on. Microsoft have happily issued an implementation of
XML-Data that we all know will have to change, as well as an
implementation of XSL that has changed already and will have to change
again. I don't mind that - I accept that things are still evolving. In
fact I'm very grateful for having the chance to build a test system
around XML-Data, even though I know it will all change. It's even got to
the point where for our own purposes I don't even use DTDs anymore - I
automatically generate schemas from my database and use your excellent
But your misplaced paternalism is now preventing me from doing real work
with information from people who still DO use DTDs - like the W3C, for
example! I want to apply XSL to XHTML, and I can only think that to do
it I will have to change parsers (unless you tell me there is a secret
switch somewhere, to turn this ridiculous 'feature' off).
