    ** 001 CA  20190526 First version, stubs taken by converting the skeleton using FWD.
    ** 002 IAS 20190527 Added multipart support.
    ** 003 CA  20191024 Added method support levels and updated the class support level.
    ** 004 ME  20200413 Clean-up and fix toString legacy method.
    **         20201125 Set header value 'fluent', use substitute for toString.
    ** 005 CA  20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy signature.
    **     OM  20210917 Code maintenance.
    **     CA  20220120 Do not used TypeFactory.object when the OO reference must not be tracked or registered.
    **                  Do not use TypeFactory.object for internal usages, use ObjectVar if the reference must
    **                  be tracked.
    **                  All TypeFactory.object variable definitions must be done outside of the top-level block.
    **     ME  20210929 Add body to string representation (if valid).
    ** 006 CA  20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
    **                  dropped if is a no-op.
