    Description

      The line "<ref x="1" y="4"/>" in the sample XML file should produce an error.

      With Xerces 2.5.0 the following error is reported:

      Key 'test_keyref' with value 'ID Value: 1,ID Value: 4' not found for identity constraint of element 'test'

      2.6.0 works like 2.6.2, so the difference is introduced between 2.5.0 and 2.6.0
