Problem conclusion

• The component that loads and assembles XML Schemas sometimes
  need to create copies of the container objects to reuse schema
  components. When the copy occurs, other container objects that
  reference the original container object need to be updated to
  reference the new copy, to maintain consistency within the
  schema. There are cases where a copy is made but the
  references still point to the old object. When a schema
  containing these objects is used in the XML Feature Pack, it
  gets confused by the duplicate objects.
  
  The fix is to ensure the schema is always consistent by
  updating all relevant references when a container object is
  copied.
  
  
  The fix for this APAR is currently targeted for inclusion in
  XML Feature Pack 1.0.0.9. Please refer to the Recommended
  Updates page for delivery information:
