    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.
