Depends on just what sort of "logic". Mike Olson, for example, wrote a
Web-based cribbage game in XSLT (as a 4Suite demo). I'm seen even more
outrageous things. I think that the balance between what should go into the
templates and what should go into support code is largely a matter of taste,
and XSLT is certainly far more sophisticated than the average templating

I think he's including language in his concept of platform, which is not
unreasonable. XSLT does have the advantage that it is implemented in many

As I mentioned, XSLT is more sophisticated than most other templating tools.
Don't forget XSLT's extension framework. I wouldn't say it can generate *any*
Web page (way too strong a statement), but I would say it can generate almost
any Web page I have personally encountered.

I wouldn't say there were many Python/XML customers out there. But as with
everything, it depends on where/how you look.
