  ****************************************************************
  This APAR introduces a new capability to DFHJS2LS. It adds
  support for a set of keywords that have not previously been
  supported. Those keywords are: 'oneOf', 'anyOf', 'allOf' and
  'not'. If a JSON schema is processed that contains these
  keywords, the different paths through the schema are merged
  together and simplified into a form suitable for a CICS
  application to interact with.
  

Problem conclusion

Temporary fix

Comments

• Prior to this APAR, JSON schemas that contained these keywords
  were rejected as unsupported. This APAR adds toleration for the
  keywords by merging the options associated with them into a
  simplified form.
  
  The process of simplifying complex logical expressions can
  result in a loss of clarity. For example, a value described in
  the schema as being either an integer between 1 and 5, or an
  integer between 7 and 10, may be simplified into a copybook
  field that supports integer values between 1 and 10. CICS does
  not enforce that validity constraint during data transformation
  - if an application uses a value that is invalid with respect
  to the schema, such as the value 6, that will not be detected by
  CICS.
