The latest XDS tool kit version 7.6.0 is still referring the one of the old code "SUMMARY" classificationScheme=urn:uuid:41a5887f-8865-4c09-adf7-e362475b143a (classCode) which does not exists in the latest codes.xml file.
Toolkit reference load document request test cases:
Test: 12346 : Initialize Registry for Stored Query Testing
Test: 12374 : Initialize Registry for Stored Query Testing - different Patient ID
Suggested fix (Lynn) Change code "SUMMARIES" back to "SUMMARY"
