This is not true. Stylesheet creation is not general purpose programming.
It is more akin to other types of special-purpose programming: database
apps (VB, Powerbuilder, Python), text processing (Perl, Python) and so
forth. I would be quite annoyed if I had to treat small extensions to my
stylesheet as if they were large software engineering projects: declaring
types, declaring variables, declaring exceptions, etc.

This paragraphs seems to be quite a fallback from your previous one. First
it was "ECMAScript is all wrong" and then "well, maybe Java is not quite
right, but it is really easy to implement." I think that XSL should be
completed with an ECMAScript automation language for now, because it is
much closer to the right thing than Java is. Stylesheet developement is
not general purpose programming. If you want to use Java for XML
processing, there is a rich and robust set of tools that allow you to do

ECMAScript is also designed explicitly to be embedded. Java is not. A Java
program is defined as a series of Java classes. Are you going to put a
class in each XSL rule??? That doesn't seem right.
