Is there a discussion about this somewhere? After reading that 
article I immediatly thought something along lines:

Accept-xmlns: http://www.w3.org/1999/xhtml;q=1.0, 
http://www.w3.org/2000/svg;q=0.9, 
http://www.w3.org/1998/Math/MathML;q=0.7

I can still vision quite long Accept-xmlns headers: perhaps some 
kind of abbreviated form should be allowed. For example:

Accept-xmlns: */xhtml;q=1.0, */svg;q=0.9, */MathML;q=0.7
or
Accept-xmlns: W3/xhtml;q=1.0, W3/svg;q=0.9, W3/MathML;q=0.7

After all, highly probably all widely used namespaces are defined by 
W3C and the rest can be referenced with full official namespace.

How the UA should express that it can render generic XML+CSS - or 
some other stylesheet language?? Yet another header?
