"A start tag whose tag name is "svg", if the current node is an annotation-xml
element in the MathML namespace."

The HTML5 parser only allows <svg> or MathML in <annotation-xml>. Not HTML.
<span> will be in MathML namespace.

We could change the parser to allow HTML there (like it allows HTML in MathML
<mi>), but then it would break MathML in <annotation-xml>. The MathML spec has
an example with MathML in <annotation-xml>.

Maybe we need a special tag that enables HTML in <annotation-xml>? <div>? It
means MathML can't have a future element called <div>.

"A start tag whose tag name is "svg" or "div" if the current node is an
annotation-xml element in the MathML namespace."

However... The XHTML version doesn't use <annotation-xml> at all. Why does the
HTML version? Shouldn't it use <mn> or <mtext> instead?
