Test case Constr-cont-charref-2 applies. 8253 1 chamberl 2006-02-14 01:16:00 +0000 Andreas, On 01 Feb 2006, the Query working group considered your comment and agreed that a character reference that is syntactically correct but does not identify a valid character should raise an error. The error code will be XQST0090 and the message will be "Character reference does not identify a valid character in the version of XML that is in use." If you find this resolution acceptable, please mark the Bugzilla entry closed. If we do not hear from you, we will close the entry at the end of February 2006. Regards, Don Chamberlin (for the Query working group) 8256 2 carmelo 2006-02-14 14:23:41 +0000 Don: I am taking over Andreas work for now. Bug closed and correct code used for test suite. Thanks for the work. Carmelo Montanez
