It would seem so, at least exporting from the browser. It still leaves the case of integrating externally generated MathML or SVG into an HTML5 page in an editor (tho' browser's built-in editors could also convert). Presumably those of us that work in XML could use a standard XSL to dumb-down m-<Backspace> re-serialize the MathML & SVG when converting to HTML5. Is that good enough? I dunno; only if the payoff is high. My fellow Math WG'ers may hate me for saying this, but provided there _is_ an unambiguous mapping between the two serializations, and providing such conversion is _required_ to be in (at least) the browsers, frankly it really doesn't matter how offensive the HTML5-ized Math is. Give me a stylesheet and I'll never even have to look at it :> [Note that "unambiguous mapping" excludes the case of nonsensical Math, like fraction(1,2,3) (whatever serialization)] > Jeff -- bruce.miller@nist.gov http://math.nist.gov/~BMiller/Received on Monday, 31 March 2008 16:49:19 GMT
