IT47319: SCHEMAS WHICH HAVE THE SAME NAME ARE ALWAYS REMOVED FROM SCHEMA COMPILATION EVEN IF THEY ARE DIFFERENT.

APAR status

• Closed as program error.

Error description

• When generating a binaryIR file from a schema duplicate schema
  definitions are removed before presenting the results to the
  schema compiler to prevent clashes. Schema files are only
  supposed to be considered duplicates if they have a matching
  hash however in some cases they can be considered duplicates if
  the have the same file name but are located in a different sub
  directory even if the files have different hashes.

  hash however in some cases they can be considered duplicates if

  In some cases this will cause the schema compiler to be unable
  to find some elements in the schema resulting in the error:

Problem conclusion

• The schema compiler will now track a list of hashes for each
  file name found and will only discard identical schemas if they
  match one of the hashes in the list.
