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

I imagine Lutz's underlying question (at least, it would be mine, and
his and our project have similar goals) is something like this:  When
an annotation is actionable, is it reasonable for a community of
practice to act as though the actions derived from B1 are applicable
only to T1, those for B2 only to T2, etc.

One thing that is a little unclear to me is what Lutz means to model
by the bundling that would make it different from modeling each
Target/Body as a separate annotation.  Presumably, that is what must
be preserved by an interpretation of an action to be taken.

I wonder if the following is a simple scenario, motivated by
oa:editing,  about which the Context model can be applied for
examination:

T1 a manuscript meant to be with UK English spelling
T2 a manuscript meant to be the same work  differing only in  U.S.
English spelling

B1 carrying an assertion that a specific occurrence of "color" should
be "colour"
B2 carrying assertion that a specific occurrence, \\\corresponding to
the above one/// of "colour" should be "color"

For this scenario, I can't exactly see why the motivation oa:editing
wouldn't just as reasonably be met with two separate annotations, so
it needs more(?) to fit Lutz' problem.
