MathML DTD warning is incorrect

The problem is that the validator accepts the MathML 2.0 
working draft version of the DTD:
 
http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd

but issues a warning for the the official latest MathML 2.0 
recommended DTD (see section A.2.3 of the recommendation) : 

http://www.w3.org/Math/DTD/mathml2/xhtml-math11-f.dtd

This is backwards.  There is only one DTD that is correct
for a document that claims to be MathML 2.0.  

Any document trying to validate as MathML 2.0 that is still 
using the working draft DTD should be given a warning and 
told what the correct final version DTD is.

This also means that "Bug 6574 - Allow multiple System 
Identifiers as acceptable for a given PI" 
located at: 
http://www.w3.org/Bugs/Public/show_bug.cgi?id=6574
should be marked as invalid.  

Documents that validate to a Working draft copy of a standard 
should be issued warnings for all deviations form the latest 
final recommended version of a standard.
