[Brian] There is a great deal to be learned from EDI and back-office
integrations on how to handle this.  Big hint: documents are yet just
another presentation of information just as a UI is a presentation of
information.  Those who tie themselves to native implementation of standard
representation models of the information may find it difficult to adjust to
changes in the models as they version over time.

1.  I always thought the Core Component's charter to be that of providing a
methodology for discovering core components NOT delivering core compenents.
This is a huge distinction.
2.  I'm not sure what you mean by "just pick them up and start using the
natively."  As I mentioned above, "there is a great deal to be learned from
EDI and back-office integrations."

It's good to state this and restate this (and is in line with my "big hint"
above).  Of course, what we will see in many cases is just the opposite of
this as time-to-delivery schedules and poor design result in implementations
with a high meintenace cost.
