This is true, and I haven't seen the code (or can't recall it in any 
case), but Mike forgets to mention the general possibility 
(likelihood) that a 2.0 stylesheet uses constructs in either XSLT or 
XPath that aren't supported in 1.0. Which is largely the point, of 
course. Such as xsl:for-each-group, xsl:analyze-string, fun XPath 
2.0, xsl:next-match, cool applications of modes, and what not. And 
those will need rewriting.

The easiest way of finding these is to run the code in a 1.0 
processor and reading the error messages. Other methods include using 
an XSLT IDE for 1.0 (also easy, and you can find the issues faster, 
but it requires the toolkit) and consulting the literature (not so 
easy, as you have to look for things that aren't there in 1.0, but 
possibly informative).

Cheers,
Wendell
