I must admit that, within the world of annotations, I struggle making 
a difference between these two… Which makes me think that we should 
not, at least for now, differentiate between them.

> Honestly, I've gone 'round and 'round  on this one... Either seems 
appropriate. One could consider the "larger work" to be the "total 
population of entities for which the object can [sic] considered to be
 relevant" OR one could think of it as "the context within which the 
object exists or an activity was performed." However, I do believe 
that (given those), context (as defined in AS2) would be more correct 
for a reply annotation--in that the original document may not actually
 be available when the reply is made...nor even of interest to the 
author of the reply annotation.
