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.Received on Sunday, 3 May 2009 21:08:33 GMT
