Hi Elena Concerning the math and xml, it all depends on what kind of math is used. In most cases some tex -> presentation mathml results in sub optimal results. One of the advantages of context is that one can easilly modulate on layouts, so for publishing on the web one can as well use pdf in a more screen/navigation friendly layout. It's no real problem to generate multiple instances from one document using processing modes. That way you get quality on paper and on screen.
