"An Aggregation does not have a representation..."
"the Aggregation URI A-1 must yield or lead to a Resource Map when
dereferenced."

Is this still the current thinking? If so, what's wrong with Resource
Maps being accepted as representations of the Aggregation?

I understand that a Resource Map is a description of an Aggregation
and not the Aggregation itself. This is true in the same sense that a
metadata record is not the same as a book. Nevertheless, it is fair to
say that a metadata record is a reasonable representation of a book.

If this was accepted, the questionable reference to an Aggregation
being a "non-information resource" could be dropped.
