In MagicDraw one can use Components as logical and graphical wrappers WITHOUT STEALING OWNERSHIP by placing a Component in the diagram and moving other elements into it. This is effective technique for organising diagrams. Since in this example the «requirement»s are organised by containment, the wrapper Components have been stereotyped as  «containment» wrappers.

While this is already more graphically stable and the concepts better quarantined than the previous diagram using only containment operators, it does requires some extra work. See however next how to apply «requirement» directly to a Component (non-standard).
