According to 
Mathematical Markup Language (MathML) Version 2.0 (Second Edition)
W3C Recommendation 21 October 2003A.2 Using the MathML DTD
            A.2.3 MathML as a DTD Module a document should contain the doctype declaration
               <!DOCTYPE html
    PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"

But if this is doctype is used the validator at

gives the following warning:

Mismatch between Public and System identifiers in the DOCTYPE declaration
    This document uses an inconsistent DOCTYPE declaration. 
    The Public Identifier  
	-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN declares the 
	XHTML 1.1 plus MathML 2.0 document type, but the associated System Identifier
	http://www.w3.org/Math/DTD/mathml2/xhtml-math11-f.dtd does not match this document type.
	The recommended System Identifier 
	for XHTML 1.1 plus MathML 2.0 is http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd.
	The safest way to use a correct DOCTYPE declaration is to copy and paste one from the 
	recommended list 
	and avoid editing that part of your markup by hand.
This contradicts the Latest MathML Recommendation.
