You want the HTML spec to say that mappings for MathML and SVG, if any, are to be found in the specs for those languages? Isn't that obvious? Why would the HTML spec say anything at all about other languages, other than where they integrate with the parsing and content models?
Comment 2 Jim Jewett 2009-09-22 19:49:47 UTC 
It is more clear than it was a few months ago, but ... no, it still isn't as obvious as it should be, because the HTML spec is still making changes and clarifications to MathML and SVG as part of the embedding.

For example, in section 3.1.4:
 "HTML, SVG, and MathML elements define which classes they are in" 

or section 4.8.15 MathML:
 "User agents must handle text other than inter-element whitespace found in MathML elements whose content models do not allow straight text by pretending for the purposes of MathML content models, layout, and rendering that that text is actually wrapped in an mtext element in the MathML namespace."


Given this, I believe it is appropriate to state that the svg and math elements (and their children) -- even when embedded in a HTML document -- get all their semantics (explicitly including their aria-* semantics) from the respective standards.

In 4.8.15 and 4.8.16 it is enough to say that the semantics are unchanged.  

In the aria pullout section (3.2.6) there is an implication that all aria/native semantics needed for a HTML agent are grouped together.  It should be explicit that this is not the case, because there may be additional semantics coming from the MathML or SVG specs.

Checked in as WHATWG revision r3976.
Check-in comment: Mention that MathML and SVG semantics are defined in their relevant specs.

Comment 4 Ian 'Hixie' Hickson 2009-09-22 21:29:33 UTC 
Ok, I added a note to the MathML and SVG sections saying that their specs define their semantics.

I haven't mentioned anything explicitly about ARIA because it seems like that would be implied by the above.

Comment 6 Jim Jewett 2010-03-15 04:14:20 UTC 
I would still prefer a note in the ARIA section that the ARIA requirements for SVG and Math elements are still defined by those specs, even when the elements are profiled by HTML.
