[Bug 2219] identity constraints and xsi:nil

Tim,

You raised this issue [1] back in 2003. Sorry for taking so long to 
respond to you.

The Schema working group has recently dealt with this issue in the context 
of XML Schema 1.1 [2].

The specific changes will be available in the next revision of the XML 
Schema 1.1 structures working draft.

We would be very grateful if you would indicate whether the disposition is 
satisfactory to you, either by responding to the bug entry [2] (close or 
reopen it) or respond to this note (if you don't already have a W3C 
Bugzilla account).
