The old recommendation was: http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd the news recommendation is: http://www.w3.org/Math/DTD/mathml2/xhtml-math11-f.dtd The question is, should a document be validated if it follows the old recommendation, or should it be rejected unless it follows the latest recommendation? 55900 4 ville.skytta 2011-08-26 20:19:37 +0000 Thank you for the reference!

The way I see it, what the system id is does not matter wrt. validity. This is how it currently is in the validator; validator does not "reject" documents that use the old system id, it just issues a warning about it. I think this is just fine, and I'm inclined to leave things as they are and close this bug. I don't see anything in the MathML specification that would actually *mandate* using any particular system id - it's a "should" in a section that is not marked as normative unless I missed something. However, the warning emitted by validator points to a document that has the old location for the MathML DTD: http://www.w3.org/QA/2002/04/valid-dtd-list.html I'll try to find someone who can update it.
