Not that the other browsers (apart frm IE) fetch the DTD anyway.

Understood. But that defeats the idea to have a single master 
document that you can maintain and serve directly...

Indeed, but this is a problem that goes beyond how an attribute gets set.



<!DOCTYPE foo SYSTEM "whatever" [
<!ATTLIST foo xml:space #FIXED "preserve" >
]>
<foo>

... should also work (at least in theory).



In general, multiple declarations for the same attribute are allowed 
in DTDs, and the rule is "first declaration wins". So a declaration 
of xml:space in a document's internal subset should override (when it 
does not simply supplement) a declaration in an external DTD. (See 
http://www.w3.org/TR/REC-xml/#attdecls.)



This means that formally, there should never be a conflict, although 
no warrant can be made either for (a) processing that relies on other 
declarations or the lack thereof, and (b) parsers that are less than 
conformant in their behavior.



What's the problem in the case of the RFC2629 DTD? How is this 
problem manifested in the browser?
