    ** -#- -I- --Date-- ---------------------------------------Description----------------------------------------
    ** 001 MP  20200603 First version, stubs taken by converting the skeleton using FWD.
    ** 002 MP  20210105 Add code in Registry and GetWriter methods
    **     ME  20210208 Fix static registry property initialization.
    **     CA  20210219 OO input parameter definitions for functions/procedures must not register with  ObjectOps
    **                  - TypeFactory.initInput will take care of this.
    ** 003 CA  20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy signature.
    **     ME  20210301 Added class 'referent' for static methods, always use registry getter.
    **         20210310 Added missing implementation (OE12.2).
    ** 004 ME  20210519 Fix registry lazy loading.
    ** 005 CA  20230817 Removed ObjectOps.register, as this registration is handled by runtime.
    ** 006 CA  20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
    **                  dropped if is a no-op.
