  New JAXP TCK 1.2 test
api/xml_schema/structures/IdConstrDefs/fields/fields002/fields00203m/fields00203m2.html#Negative
 
fails because xerces doesn't detect identity constraint violation in
the document below.

In the test the both fields have local type decimal and values "3.0" and "3".
While the lexical representations differ, the values are equal. So the
uniqueness constraint is violated and the test expects the validator to
report the error.
 

The specification (XML Schema Part 1: Structures,
3.11.1 The Identity-constraint Definition Schema Component) reads:
"The equality and inequality conditions appealed to in checking these
constraints apply to the value of the fields selected, so that for example
3.0 and 3 would be conflicting keys if they were both number, but
non-conflicting if they were both strings, or one was a string and
one a number."

Note then if type of the field "number" in element declaration is
specified as "xsd:decimal" instead of "xsd:anySimpleType"
the violation is detected.

The test's schema is:
-------------------------- fields00203m2.xsd
<?xml version="1.0"?>
<xsd:schema
  xmlns="IdConstrDefs/fields"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"

          <xsd:selector xpath="./number"/>
          <xsd:field xpath="."/>
      </xsd:unique>

</xsd:schema>
