+0.5 -- What does this do to the multiplicity body types (e.g., choice,
composite, etc.)? Are you also proposing to absorb those into the
SpecificResource as sub-classes? Are we left with a nesting set of
SpecificResources? The text of the proposal is unclear. I'm also not
certain that we've considered how this change propagates through various
bits and pieces of the model.

-0 -- As mentioned above, we already have multiple body/target types for
multiple bodies/targets (i.e., choice, composite, etc.). I'm not sure I see
a down side to adding another one specifically designed to encapsulate
strings.

-1 -- I'm still trying to wrap my head around this one. Is our intent to
say that bodies and targets are content containers (i.e., little more than
objects)? Is that a different implication than what was implied by
hasSource (i.e., this thing was derived from this other thing)? I feel like
things only get weirder as you layer on other features like selectors. For
instance, we have a specific resource which is scoped and defined by a set
of selectors and then we say it "hasContent" and by that we mean the
resource from which the SpecificResource was selected from. The semantics
are very odd. If folks don't like hasSource, I'd suggest using something
like 'derivedFrom' or anything else that suggests that my specially
selected sub-portion of a resource is not, in fact, the content of the
whole resource.

I'm also starting to feel like the entire discussion about roles on bodies
and the need to do this using a SpecificResource is distracting us from the
true purpose of the SpecificResource. In the first place it was developed
as a means to identify sub-portions of resources that serve as the target
portion of the annotation and then extended to the Body on the grounds of
symmetry. I think it's okay to extend its use to capture role information
but renaming the hasSource predicate has some implications for the other
(more common) usages of SpecificResource.
