    --           i.e. with its header determined from Protocol

    SignType returns Signature from IFSelect;
    ---Purpose : Returns a SignType fit for STEP (creates the first time)

    NewSelectSDR returns SelectSignature from IFSelect;
    ---Purpose : Creates a Selection for ShapeDefinitionRepresentation
    --           By default searches among root entities

    NewSelectPlacedItem returns SelectSignature from IFSelect;
    ---Purpose : Creates a Selection for Placed Items, i.e. MappedItem or
