      Description

      A DESCRIPTION OF THE PROBLEM :
      The Java schema validator does not find an error in an invalid XML file.

      Output of Validator of XML plugin of Notepad++:
      ERROR: Element '{http://www.example.org/root}CollectionMember': No match found for key-sequence ['object1'] of keyref '{http://www.example.org/root}Collectiontype_defined'.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Compile attached program
      2. Place attached XSD and XML in same folder as compiled program
      3 run program: java Test schema.xsd invalid.xml

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      An execption should be printed since the referenced type ("object1") is missing in "invalid.xml" (see "valid.xml" for a valid file).
      ACTUAL -
      No exception occurrs.
