private class Scope from TNaming 


    ---Purpose: this class manage a scope of labels
    --          ===================================


uses Label      from TDF,
     LabelMap   from TDF,
     NamedShape from TNaming,
     Shape      from TopoDS

    Create
    ---Purpose: WithValid = FALSE
    returns Scope from TNaming;

    ---Purpose: if <WithValid> the scope is defined by the map. If not
    --          on the whole framework.
    returns Scope from TNaming;    

    Create (valid : in out LabelMap from TDF)
    ---Purpose: create a scope with a map. WithValid = TRUE.
    returns Scope from TNaming;

    ---Purpose:  Returns  the current  value of  <NS> according to the
    --          Valid Scope.
