XForms CR - 7.5 - Which data types in XForms functions?

I suggest that the second line of 7.5 be revised to read, "In addition, a 
conforming XForms processor is required to support the functions described in 
7.6 to 7.8. References to data types in those functions are to XPath 1.0 data 
types.".

At present I assume that the XForms functions in 7.6 to 7.8 use XPath 1.0 
data types but it seems to me that it would be an improvement to state it 
explicitly.
