Re: incorrect warning message

Now for the bad new:

The old DTD
http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd
is not a valid document.  

If a document with this DTD tries to CSS validate at
http://jigsaw.w3.org/css-validator/

The following error occurs:
-**-
Please, validate your XML document first!

Line 239

Column 15

A colon is not allowed in the name 'IS10744:arch' when namespaces are enabled. 
-**-

I reported this to www-validator-css@w3.org Tuesday, 16 December 2008.

I just now tried rechecking the a MathML document with the old DTD and got the following error for CSS validation

-**-
Target: http://www.mozilla.org/projects/mathml/demo/texvsmml.xhtml

I/O Error: /usr/local/Jigsaw/Jigsaw/WWW/css-validator/org/w3c/css/util/xml/mathml/xhtml-math11-f.dtd (No such file or directory)   
-**-

Please look into fixing this problem.
