Description Don Chamberlin 2008-05-19 18:41:04 UTC 
During the analysis phase, err:XPST0005 is raised if any expression other than () or data() has a static type of empty-sequence(). But all updating expressions return empty sequences, and we do not want all updating expressions to be static errors. In the Update spec, Section 4 (Static Typing Feature) should state that err:XPST0005 does not apply to updating expressions.
Comment 1 Don Chamberlin 2008-06-03 17:39:17 UTC 
The Query working group discussed this bug report on 3 June 2008 and agreed with the suggested change. The Update spec will specify that updating expressions, although they return empty sequences, are not static errors.
