Local fix

• WTXCQ - WTX00036950
  CH / CH
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender customers using classic XML
  importer
  
  Problem Description:
  Classic schema importer would create invalid type tree when
  schemas contained empty groups or groups contain just a sequence
  and no elements.
  
  Platforms Affected:
  ALL
  

Problem conclusion

• Corrected classic schema importer to properly remove empty
  groups. Previously classic importer would leave empty groups
  when there was only 1 sub object and that sub object was a
  sequence.
