      Description

      Name: eaR10174 Date: 02/09/2004


          RI incorrectly evaluate fields of identity constraints like 'node_name/.'. RI reports
      that an element has a key with no value. Fields like 'node_name' are evaluated correctly.
      According to the XPath specification expressions 'node_name' and 'node_name/.' are the same.

      The bug affects the following new JCK-15 beta2 test adopted from W3C XSTC-20020116 testsuite:

         api/xml_schema/msxsdtest/identityConstraint/idL077.html#idL077_i

      The sample is provided below; it fails on JDK 1.5.0-beta-b37.
