John,

Nothing in a quick skim through the Introduction seems to me to contradict 
what I wrote earlier.

Was this the section you were referring to? ...

"Both XSLT and XPointer extend XPath by defining additional functions; some 
of these functions operate on the four basic types; others operate on 
additional data types defined byXSLT and XPointer.".

The quoted section indicates that XSLT and XPointer provide mechanisms for 
extension functions.

I see no reference to "extension functions" which are "XPath extension 
functions". If the XForms CR wishes to refer to "XSLT extension functions" or 
"XPointer extension functions" that's fine by me. I just think it may be 
incorrect for the XForms CR to refer to those as "XPath extensions 
functions".

On reflection, do you agree?

Regards

Andrew Watt
