If you look at the XSL WD, it's clear that the semantics of both the tree construction part and the formatting objects part have diverged significantly from DSSSL (and will probably diverge further), so I don't think this is a practical approach. This raises the question of how Jade should evolve. I would like to be able to use the tree construction part of XSL with all the Jade backends. Since the Jade .fot output is XML, you can use XSL to create it, so all that's needed is a program that takes the .fot Jade output and feeds it to any of the existing Jade backends. You could do this to some extent using Jade itself together with an appropriate stylesheet, but it would be much better to hook up expat to feed the backends directly. The FOT format would need to evolve a little bit but hopefully not much. One problem is that in XSL inheritance is done in the backend; thus the FOT format needs to have some simple way to express inherited characteristic values. Another useful component would be something that translated from the standard XSL flow objects (once they've matured a bit) into the Jade .fot format. If support for the XSL flow objects becomes available, then it would also be useful to have a Jade backend that generates XSL flow objects.
