  ****************************************************************
  Original data corruption after moving a copy can occur in 2
  ways:
  1) Original references are not always broken before moving a
  copy into another structure. As an example, this would make
  FastAccessCursor not be able to distinguish a copy from an
  original.
  2) A flag was not being consistently set by xci's
  CacheManager.
  

Problem conclusion

• The algorithm has now been corrected to fix the issues
  described above.
  
  The fix for this APAR is currently targeted for inclusion in
  XML Feature Pack 1.0.0.15. Please refer to the Recommended
