On page 2-14, you can see that the relation between Association and
AssociationEnd is a composition. The semantics of a composition is, that
there can be at most ONE composit.
The multiplicity at Association (1 , NOT 0..1) states that every
AssociationEnd must have an Association as composites. So, it is implicit,
that there can be no other composites than Association, especially not a
Namespace. (page 2-13 shows, that the relationship between Namespace and
ModelElement is a Composition as well, but with multiplicity 0..1, which
means that a modelelement may have a namespace.)
