RE: A list of useful functions that aren't in the core

http://fxsl.sourceforge.net/
http://www.exslt.org/

these are complimentary. Fxsl implements functions in xslt, exslt
defines a list of functions and implementation guidelines so that one
can have extention functions not otherwise in the core. Saxon and if I
remember correctly Xalan both implement the exslt core functions.
