I think there are two things you're suggesting here. You're suggesting
that XSL be extended to have a JS mode, where the output of the
function is the result of executing the JS?

Then it also sounds like you want a way to define a template match
using JS. I don't think this is a good idea. If you support the
function idea then you can embed functions in a template match any
way.

Adding a function to XSL to evaluate JS should be quite easy to do.
I've added a couple myself already now.

PD> record in the form of a JS object.
