Add Schema.org accessibility metadata to enable discovery of accessible math content

[gcapiel]

Encapsulate math expressions with the new Schema.org accessibility properties that indicate the use of MathML or LaTex, so search engines can identify pages that have accessible math.

http://a11ymetadata.org

Example:
< span itemscope itemtype="http://schema.org/WebPageElement">
< meta itemprop="accessibilityFeature" content="latex">
< meta itemprop="accessibilityFeature" content="MathML">
< div class="MathJax_MathML" id="MathJax-Element-1-Frame">
...
< /div>
< script type="math/tex; mode=display" id="MathJax-Element-1">df(X_t)= \sum_{i=1}^d f_{,i}(X_t),dX^i_t + \frac{1}{2}\sum_{i,j=1}^d f_{,ij}(X_{t}),d[X^i,X^j]_t</script >
< /span >

Though, the source is in LaTex, because MathJax allows you to get the corresponding MathML, I have also tagged the formula as being available in MathML.

All sounds sensible. Do you have a patch?
