Description Priscilla Walmsley 2013-02-02 17:57:59 UTC 
The xs:QName constructor function, unlike all the other type constructor functions, has a signature that does not allow the empty sequence as an argument, although it can return the empty sequence.   Is this inconsistency an oversight?  I cannot find any text that explains why it would be different.
Comment 1 Michael Kay 2013-02-03 11:47:43 UTC 
Thanks for pointing this out. The error arose because of incomplete application of the change that brought the xs:QName constructor function into line with other constructor functions in 3.0, by removing the restriction that the supplied argument be a string literal. I have fixed it as an editorial error, but have included a mention in the Changes appendix.
