      Description

      Name: inR10064 Date: 02/18/2004


      The method
          public Schema newSchema(File schema)

      of the class javax.xml.validation.SchemaFactory does not detect
      violations of the "Schema Component Constraint: Element Declarations Consistent"
      defined in section "3.8.6 Constraints on Model Group Schema Components"
      of XML Schema 1.0 Structures spec :

            If the {particles} contains, either directly, indirectly (that is, within
            the {particles} of a contained model group, recursively) or ?implicitly?
            two or more element declaration particles with the same {name} and {target
            namespace}, then all their type definitions must be the same top-level
            definition, that is, all of the following must be true:
                1 all their {type definition}s must have a non-?absent? name.
                2 all their {type definition}s must have the same name.
                3 all their {type definition}s must have the same target namespace.

      See the sample and log below. Test schemas of the affected JCK 15 tests contain
      definitions like:
                      <xsd:sequence>
                              <xsd:element name="e1" type="xsd:string"/>
                              <xsd:element name="e1" type="xsd:integer"/>
                      </xsd:sequence>

      which are processed without errors.

      The bug found in the JDK 1.5.0-beta-b38. The bug affects the following
      new JCK-15 beta2 tests adopted from W3C XSTC-20020116 testsuite:
