Re: May a Specific Resource be object of the oa:hasScope relationship ?

Sorry, I wasn't clear.  All of the resources apply together as a
single composite resource.

The distinctions, given two bodies B1 and B2 and a single target T1:

* Multiple uses of hasBody:   Each applies individually.
    B1 annotates T1, B2 annotates T1
* Choice:  All apply, but only one needs to be treated at any point in time.
    (B1 or B2) annotates T1
* Composite: All apply together as a single whole.
    (B1 and B2) annotates T1
* List: All apply together as a single whole, and in a particular order
    (B1 then B2) annotates T1

Thus (B1 annotates T1 and B2 annotates T2 and-not B1 annotates T2) is
not possible to express within a single annotation. It is necessary to
express this using multiple annotations, even if the annotator and
annotation creation time and process is the same for both of them.
