  ****************************************************************
  If XSourceResolver returns a mix of different Source types
  when preparing a stylesheet and its imports and includes, such
  as DOMSource and StreamSource instances, repeated parsing of a
  stylesheet may occur.  This will lead to a StackOverflowError
  (if systemIds are not set on the sources) or circular
  definition error such as the following:
  
  FATAL ERROR:  IXJXE0019E: [ERR XS1026][ERR XTSE0180, ERR
  XTSE0210] It is an error to use circular definitions on
  xsl:import or xsl:include instructions. The stylesheet
  '<stylesheet_uri>' is already loaded.; SystemID: unknown;
  Line#: unknown; Column# unknown
  

Problem conclusion

• The problem has been eliminated, such that an XSourceResolver
  may freely mix Source types for a single stylesheet.
  
  This APAR is currently targeted for inclusion in the Feature
  Pack for XML 1.0.0.7.  Please refer to the Recommended Updates
