I think we discussed this back then in the initial ItemList thread on this list - and the motivation on why to have indirection in here is that ordering and sequence information are typically context-bound and not absolute properties of the underlying entities.

I believe in this case the indirection has value since the ListItem can carry ordering information without it being merged in with other different ordering properties being used with the same real world item. These issues were responsible for RSS1's awkward use of an rdf sequence structure BTW.

Authors don't seem to use multiple types much, but I wonder if that is because we don't give them clear examples of how and when to do that.
