APAR status

• Closed as new function.

Error description

• Programmatic construction of Service Data Objects uses the
  same internal representation that is used when data objects
  are deserialized from an XML stream, which can be inefficient
  when accessed directly via SDO APIs.

  Programmatic construction of Service Data Objects uses the
  same internal representation that is used when data objects
  are deserialized from an XML stream, which can be inefficient
  when accessed directly via SDO APIs.
  

Problem conclusion

• Functional improvements have been made to allow for efficient
  programmatic (or "top-down") construction of Service Data
  Objects, which also form the basis of Business Objects used by
  IBM Business Process Manager 7.5 and WebSphere Enterprise
  Service Bus 7.5 in Lazy Parsing Mode. Data objects constructed
  in this manner, as well as copies made from these data
  objects, also benefit from faster navigation and serialization
  when compared to data objects that have been deserialized from
  an XML stream.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.1.  Please refer to the Recommended Updates
