I don't know what AFAP means (oh, ASAP I guess) but considering Hans  
has had MathML2 rendering in ConTeXt for years now I figure he'd  
probably have MML3 done before we decide what prefix to give our  
internal variables in the module. Or do you need a LaTeX intermediary  
for some other reason as well?
