This is an interesting grey area!  The CCR is actually setup to handle
both nouns and verbs in anticipation of a need.

Here's a thought - in the insurance industry you may have a 
core component called "maximum total liability" for a life
insurance policy and it reflects the value that the policy can
be written for.

Trouble is this is NOT a data item, its a calculation on a set of
data items that result in a data value.

Another example is "Amount Due" - which is a calculation of
(Invoice Amount, Invoice terms, Days overdue, Percentage Interest)

So you have a very well defined algorithm for calculating this,
and the definition consists of verb and noun(s).

Another example is 'Country Codes'.   This is a join between
the ISO Country codes and your customer account profile to
determine actual countries that you are allowing that 
customer to ship too...so its actually a stored procedure.

I've probably just walked into the holy shrine here of 
Core Components and darned to utter the forbidden
chant that denies the existence of the true core components.

As we just agreed you need both UML and XML, you also
need to understand that core components can consist of
nouns, and nouns and verbs.
