Hello, The spec says that mathcolor/mathbackground are accepted on all MathML presentation elements: http://www.w3.org/TR/MathML3/chapter2.html#interf.toplevel.atts <math/> and <semantics/> are not listed among MathML presentation elements, so I think mathcolor/mathbackground should not be allowed on them, and this is confirmed by the RelaxNG schema. http://www.w3.org/TR/MathML3/chapter3.html#presm.summary However, the two sentences below could be interpreted as saying that <math/> accepts mathcolor/mathbackground attributes: "The math element accepts any of the attributes that can be set on Section 3.3.4 Style Change <mstyle>" "mstyle elements accept the attributes listed in Section 3.1.10 Mathematics style attributes common to presentation elements. " and this one for <semantics/>: "semantics should be considered part of both presentation MathML and content MathML" -- Frédéric Wang. www.maths-informatique-jeux.com <http://www.maths-informatique-jeux.com> www.maths-informatique-jeux.com/international <http://www.maths-informatique-jeux.com/international>Received on Wednesday, 21 April 2010 10:28:23 UTC
