| Yes, well there appears to be some confusion in nomenclature.

Hmmm, this is interesting but disturbing. I have always assumed the UML spec
to be the authoritative source, but can see where the confusion has
occurred. Here we have a single source of teaching on the subject stating
both side of the argument at the same time !!!

If I were you, I would take the UML spec as *the* way as it has not changed
for at least ten years that I am aware of. Certainly if you are using UML to
communicate design, anyone else that knows UML should understand that
aggregation = ref and composition = value.

Dontcha just love it when two people can talk the same language and hear two
different things ?


OK, so maybe we should all talk UML :-))

white diamond = loose containment
black diamond = owned containment

And do not forget "object " depending of who and where it's said it means
either instance of type
 
No. It cannot _introduce_ more confusion since "containment by
reference" is
the exact wording used by Booch well over 16 years ago in his discussion
of
Aggregation :)
