I believe we are in agreement to use a merge ExternalClassification into a single
enhanced Classification class. We have significant differences on modelling
Path and Path element on the role of URN etc.

We agreed in RIM 1.1 that all dynamic metadata is supported at the RegistryObject
level.

The task of this sub-team is to define how to extend Classification to include
external Classification use case in a manner that is more symmetrical with internal

classification. Note that the use-case for external classifications was already
addressed using Slots in 1.0 specs
but it was not symmetrical with internal classification.

To start opening up RIM issues such as what is classifiable and what is not is
outside
the scope of the mission for this team. This team's mission is to define *HOW* to
externally
classify things and not to re-define *WHAT* is classifiable.
