Nice way to see it. I agree with all but the fact that an ACC cannot be
instantiated at all. If you assemble a form, the form itself can be
viewed as an ACC, composed by ASCCs and BCCs.

Definitely.

Agree on both.

I was voting for this approach but I have some doubts now.
- First, Association is a RegistryObject but not a RegistryEntry. So you
loose status and version control capabilities from RIM.
- Second, since you don't have an ExtrinsicObject you can't set your own
objectType attribute (ASCC/ASBIE in this case, although you can set
associationType).
- Third, in the attached document you've made the following note:
"*Note that the relationship between the "Person. Details" ACC and the
"Residence" ASCC can also be represented with a registry association.
So there are really 2 associations here."

How are you seeing this 2 Associations??? Like this?
Person. Details ACC (Contains) Residence ASCC (Extends) Address. Details
But since an Association needs a source and a target, Residence ASCC
must be a RegistryObject. would we have an Association as source/target
of another??

Classification can (only) be made based on a ClassificationScheme.
I see it so that if you have 8 predefined context categories, then you
have 8 ClassificationSchemes (containing all the posible classification
nodes!). Having all that, you can classify the BIEs (RegistryObjects).
But you still need 2 RegistryObjects (1 CC and 1 BIE) and 1 Association
between them.

Said that, I didn't get the point for the 2 paths.
