Indeed, good point. I think that would almost work out of the box with the existing implementations of renderers. However, it may easily become more intricate. Suppose the default way of rendering division (according to some *.ntn notation dictionary) is a/b instead of a --- b then the approach above would no longer work. Instead we'd have to attribute the complete (plus a (divide b c)) expression with, well, maybe some Presentation MathML fragment with placeholders that would then be replaced by the renderings of the respective arguments. Something similar to the patterns in those pattern-matching-based notations. Cheers, Christoph -- Christoph Lange, Jacobs Univ.
