    ---Purpose: Validates labels of a function in <log>.
    --          In regeneration mode this method must be called (by the
    --          solver) even if the function is not executed, to build
    --          the valid label scope.

    ---Purpose: execution of function
    --          ======================

    MustExecute (me; theLog : Logbook from TFunction)
    ---Purpose: Analyse in <log> if the loaded function must be executed
    --          (i.e.arguments are modified) or not.
    --          If the Function label itself is modified, the function must
    --          be executed.

    Execute (me; theLog : in out Logbook from TFunction)
    ---Purpose: Execute the function and push in <log> the impacted
