Reference to definition of data types missing 

Comment:

The data types 
dateTimeDuration
 and 
yearMonthDuration
 are described as XForms data types, but they are data types defined in the 
XQuery Data Model [http://www.w3.org/TR/2007/REC-xpath-datamodel-20070123/]
 specification. Please provide a reference to this specification from sec. 5.2.3 and 5.2.4. See also the 
related comment from the XML Core WG [http://lists.w3.org/Archives/Public/www-forms-editor/2007Mar/0007.html]
, which is basically the same.
