Announcing some EXSLT support for firefox 3

Hi all XSLT fans.

We now have code checked in to support some parts of EXSLT [1]. These 
functions will be supported in the upcoming Firefox 3 release (sorry, no 
chance of backporting to earlier releases)

exsl:node-set
exsl:object-type
regexp:test
regexp:match
regexp:replace
set:difference
set:distinct
set:intersection
set:distinct
set:has-same-node
set:leading
set:trailing
str:tokenize
str:concat
str:split
math:min
math:max
math:highest
math:lowest

The above functions should work in the current nightly builds. Please 
test and report any problems.
