I disagree. XSLT 1.0 was developed without the benefit of 20-binder-
thick formal semantics and it is a very clean and elegant language.
Most of its roughest spots come when it taps too rashly into some
prefabricated mess of a formalism from another language (e.g. format-
number from Java).
I would easily trust the intuition of a few (emphasis on "few")
brilliant developers for the development of try/catch rather than all
the formal huffery-puffery that has resulted in the XQuery generation of
XML languages.
Worse is better.
