I believe people discussed this after you dropped off, and they hoped you 
would be willing to take on this action item after being informed that the 
task needs doing.

Unfortunately, I wasn't in the conversation either.  I hope someone will 
speak up to clarify.

For my part, I think there's a clue in the CC structure that Mike R. 
referred to in his recent message: the difference between the primary 
content of a CC and its supplementary components.  For an element that 
directly contains characters, it would be a fairly clean and 
"deterministic" break to say that its content should be the primary content 
associated with that CC and the supplementary components should be attributes.

However, I fear that this may offer only a false hope if, for example, some 
of the supplementary components have (or would benefit from) internal 

Also, if this is such a good dividing line, it would work for non-leaf 
elements as well as leaf elements.  E.g., the primary content would be in 
the form of some structured subelements and the supplementary components 
could easily be attributes.

I think it's time for a set of examples that's varied enough for us to test 
the different scenarios.  Perhaps we can extract such a thing from the 
growing PartyExample.  Arofan, can you speak to this?
