I can see how this handles inserted and deleted text, but I don't think
it addresses moved text, where some association has to be made between
the old location and the new location.  Just having moved-deleted and
moved-added classes doesn't connect the SPANs.

This has the same problem as moved text.  A footnote is a relationship
between a point in the document and some content; meta-text is a
relationship between some content and some other content.
I haven't seen the proposal for FN, but I doubt it connects the
footnote to an area.  Leaving aside the question of non-hierarchical
areas (there is no reason a commenter's comment would identify a
region that corresponded to hierarchically convenient elements),
I think the described meta-text capabilities require making an
association between a SPAN (an area within the document) and some content.

I think to do this right you need to add LINK-REL and LINK-HREF
attributes to SPAN, to indicate a relationship between SPANs, or define
a new SPANLINK element that specifies a relationship between two
SPANs (or a more general ELEMENTLINK that connects any two elements that
have names or IDs).
