By "Attribute" you mean a property of the container?
Or is this per container entry?
Or a platform managed aspect not in the RDF?

While I like this as a principle, there are some details ...

* LDP-C have paging. RDF collections and/or containers in a LDP-R do not.

* Different member entry creation mechanisms (adding to a RDF list or 
RDF Seq is tricky at the best of times).

A flag on a LDP-C to say whether it is an aggregation or a management 
containment relationship is, in effect, having two types - an LDP-C(agg) 
and LDP-C(mgt) that share paging, adding new members, etc
