But "correctly" (according to most suggestions in this thread) doesn't
imply full xml well formed rules. everything from omitting end tags to
onmitting start tags to omitting tags altogether and allowing
<math>x+y</math> to parse to a valid mathml DOM have been on the table.

If HTML5 picks up math as has been proposed, then currently it's not
known what the answer would be, but it would be specified by the html5
parse rules, ad produce a valid mathml dom, perhaps on eof those
suggestions, perhaps <merror><mtext>146,382</mtext>... we'll see, but it
would be specified somehow, not left open.

hence this thread. To integrate MathM into an XML vocabulary takes more
or less no effort at the syntax level 9although of course applications
still have to cope with the mixed markup) but with teh monolithic design
currently being proposed for html5 with a specific parser with
per-element rules built into the parser, exteding teh vocabular needs
per-element discussion for each element to be added, hence this thread.
