Mike,

Sorry if this is rehashing an earlier discussion that I don't remember.
Why can't each version of the transclusion simply store all the data for
that version? So for behavior 1, an updated version of the transclusion
would specify different offset/location in the same version of the target
item, and for behavior 2, updated version would specify a different
version of the target item together with the location in that version.
