> There has been some brief discussion about UML's aggregation and
> composition relationships. In an indepth study performed by myself and
> Franck Barbier, we have looked extensively at this issue and find
> the current UML specification ambiguous, self-contradictory and incomplete.
> We report this in a number of articles and suggest a way forward.
> 
> There are many publications (some are listed on the OPEN website at
> http://www.open.org.au). Perhaps start with
> Black and white diamonds,
> Henderson-Sellers, B. and Barbier, F., 1999,
> <<UML>>'99 --- The Unified Modeling Language. Beyond the Standard
> (eds. R. France and B. Rumpe), Lecture Notes in Computer Science 1723,
> Springer--Verlag, Berlin, 550--565
> 
> (A longer version is in
> A survey of the UML's aggregation/composition relationships,
> Henderson-Sellers, B. and Barbier, F., 1999, L'objet, 5(3--4), 339--366  
> )
> 
> 
> More recent ideas (including suggestions for fixing UML) are in
> The whole--part relationship in the Unified Modeling Language:
> a new approach,
> Barbier, F., Henderson-Sellers, B., Opdahl, A. and Gogolla, M., 2001,
> Chapter XII in Unified Modeling Language: Systems Analysis, Design, and
> Development Issues (eds. K. Siau and T. Halpin), Idea Group Publishings,
> 185--209
> 
> Improving the UML metamodel to rigorously specify aggregation and composition,
> Bruel, J.-M., Henderson-Sellers, B., Barbier, F., Le Parc, A. and France, R.B.,
> 2001, OOIS 2001 (eds. Y. Wang, S. Patel and R.H. Johnston), Springer-Verlag,
> London, 5--14
> 
> The latest is still under consideration, but describes our proposals for 
> UML2.0 in TSE
> 
> We are also party to a formal proposal to the OMG and this can be found
> on the OMG website at
>  UML 2.0 Superstructure. Initial Submission from DSTC Pty Ltd, 
> Duddy, K. and Henderson-Sellers, B., 2001,
> OMG document ad/01-10-08, 34pp
> 
> In other words, there has been a *lot* written about whole-part. You can
> find references in any of these papers to a wealth of literature, UML, OO
> and non-OO
