    ** 001 IAS  20190923 First version.
    ** 002 MP   20200701 Improve methods like legacy class
    ** 003 CA   20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy

    **     CA  20210609 Updated INPUT/INPUT-OUTPUT parameters to the new approach, where they are explicitly
    **                  initialized at the method's execution, and not at the caller's arguments.
    ** 004 CA  20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
    **                  dropped if is a no-op.
