No, it's not intentional, it's a muddle. Something we still need to sort out. There are basically two schools of thought here: (a) duration as defined in Schema creates too many problems, so we should not support it in XQuery, and require people to use the two subtypes yearMonthDuration and dayTimeDuration instead. (b) we should only support a basic set of operations on durations, such as comparing them for equality and converting them to and from strings. I suspect that some people thought we had decided (a) and others that we had decided (b). Note that although we define op:duration-equal in F&O, we don't actually say what its semantics are, for example whether P1Y equals P12M. In Schema, these are distinct values in the value space.

There is an operator op:duration-equal in the F&O spec but there is no line in the Operator Mapping table of the XQuery 1.0 spec that allows you to use the "eq" operator on two values of type "duration". This seems like an inconsistency - or was it intentional? _____ Do You Yahoo!? Yahoo! <http://rd.yahoo.com/finance/mailsig/new/*http://finance.yahoo.com> Finance - Get real-time stock quotes
