I guess I meant set in a very broad sense like the dictionary says: "A group of things of the same kind that belong together and are so used". I didn't mean any mathematic abstractions. I guess it could be a bag, but that would need yet another definition then. I would propose to fix my definition by saying "A collection is an unconstrained set of ..."

You use the word "set" above. We went around the trees several times when doing ServiceGroups in OGSI on whether it was a set or a bag. A ServiceGroup is a bag. There were several cases where a service might be included several time with different metadata being important for example. In manageability, my intuition says it should be a bag, but I can't find a good use case.
