Right, any implementation should definitely work in HTML/MathML/WhateverML.

Ouch.  At the worst, it should act like a <use> element.

Okay, thanks for the useful information.  It does sound like that is not 
an ideal patch.  Maybe someone from the community who's interested in 
SVG Fonts could take a look at what it would take to create a suitable 
patch.  Is it worth them looking at that patch, or would they be better 
off starting from scratch?
