My sources are: Somebody told me so? :) Seriously, I thought that somebody told me so but I don't remember who so I could very well be wrong. But, if you think about the Corba mapping of MOF, it would be basically impossible to implement mutable CollectionTypes. The reason is the MOF implementation wouldn't have any way of knowing if you change any element. So, basically, with the Corba mapping you _might_ be able to get "copy" semantics. But, to get a definitive answer, we should ask Martin or another MOF RTF member. > to have.

Yes, this is one of the reasons that we shouldn't use StructureTypes. - Brian
