I wasn't suggesting that objects (or direct object references) be put in
the bags.  It's just that i see them for expressing relationships with
other objects, using indirect references to related objects - paths.  
(The related objects may be relationship registries, eg catalog
indexes/organization objects.)  Those paths are still strings, but they
are not textual annotations!  I think calling them Annotations would be
misleading.

I'm starting to have some sympathy for tres' original suggestion of
MementoBags.  We're talking about something we know is useful, but i have
the feeling we do not yet have a clear shared understanding about them.  
Perhaps we should go with a new, less familiar name (MementoBag or maybe
Mementos), so when we all do arrive at the shared picture, we're not
saddled with a simple, familiar, and wrong choice.

I could be wrong - i've started tracking this only recently, so it may
just be me that's got a fuzzy picture of the suckers.  Whoever is clear 
enough (and trusted enough) to specify the implementation should have the 
say, i guess.
