OpenFormula relevance

While writing up the minutes for today's call it hit me that I goofed on 
the discussion of the relevance of OpenFormula to the W3C's work.  For 
some crazy reason I mentioned XSLT as relevant.  This is not really true. 

The relevant connection would be to XPath, which has a "core function 
library", which could be supplemented:

http://www.w3.org/TR/xpath/#corelib

XForms, for example, keeps the basic syntax of XPath but supplements it 
with additional functions:

http://www.w3.org/TR/xforms/#expr-lib

OpenFormula (at least the function library) could be a another source of 
extension functions.
