Im not sure what you mean by 'stable identity', but the chief problem
with containers is the fact that there is no way to 'close' them. If I
say that FOO is a container and A, B and C are in it, there is no way
to say that this is *all* that is in it. This makes them useless for
encoding structures, eg OWL syntax. Collections' overcome this
difficulty. So the collection notion is widely used to layer higher-
level notations onto RDF, which is probably why toolkits have special
provision for them. This does not stop you using the containers, of
course. They are simple enough that you hardly need syntactic sugar,
right?

In contrast to RDF collections (rdf:List), they have a stable

Furthermore, standard RDFS inferencing can be used to infer
membership as the property rdfs:member.
Yet, most RDF vocabularies that I know of use collections and
syntaxes such as Turtle have syntactic sugar for collections, but
not for containers. Why is that?
