FXPath - A comment on EXSL

Hi,
 
As a comment on the document "User-Defined Extension Functions in XSLT" 
(called EXSL here),
written by Jeni Tennison, I've written a document about "FXPath - Functional 
XPath":
 
http://www.pantor.com/fxpath/
 
In short:
 
The purpose of this document is to outline an alternative approach to writing 
extension functions in XSLT.
The FXPath approach is based on XPath where as EXSL is based on XSLT 
instructions. The basic
idea is that functions dealing with primitive XPath types are better 
implemented in a language
close to XPath rather than by retrofitted XSLT instructions.
 
Cheers,
