Very well articulated, Wendell.

I agree with you that the technology has come a long long way and it won't
be long before XSLT is called upon to do more and more things that heavy-
weight languages do.  By discussing (the somewhat controversial) issues I
have raised and coming up with tools & solutions, we will find more and more
people adopting XSLT in serious anger.

Just as I didn't get functional programming for a long time, there are
many people who just do not get XSLT.  It is a very special language
and, serendipitously, it is turning out to be capable of solving a classes
of problems in domains which were never even though of when it
was first designed.  Remember Windows 1.0.  That was not very
successful.  Remember Windows 3.0.  Different story altogether.
The difference in maturity between between XSLT 1.0 and 2.0 is similar.
Despite still having some of difficulties I raised, the future is bright for
XSLT 2.0 as the tools and techniques for using it mature.

To be honest, I'm not that keen on programming in C++ anymore.

Cheers too.
