------- Comment #6 from mike@saxonica.com  2008-04-22 18:00 -------
Regarding comment #5: no, I disagree. An implementation of a function is always
allowed to return a value that is an instance of a subtype of the declared
return type if it chooses. That's a general rule, it's nothing specific to
these two operators. (I agree there is room for debate about whether we
currently say clearly what the general rule is here; but that doesn't belong as
part of this bug.) 

The proposed text is being drafted as erratum E23.
