The type of the XML island must be declared somehow or it would
certainly be making more tag soup. As has been stated by other posters,
you either have to duplicate MathML (or some subset of it) in HTML5 or
you have to connect it to the MathML definition. The way one references
an XML definition is by declaring its namespace. One could define that
namespace implicitly in HTML5 by stating in the HTML5 spec that <math>
means MathML 2.0 or whatever. Of course, this locks MathML to one
specific version -- not a good thing.
