Adding new properties with no semantics is a slippery slope
that I am reluctant to travel any further than absolutely
necessary.  Currently, we just have two: "comment" and
"creator-displayname".  "Creator-displayname" is relatively
well understood, and "comment" is for anything else with
no semantics.

So until we define some interoperable semantics for "status", I
believe this is much better left to a separate document describing
"interesting properties with no interoperable semantics".

   Labels won't solve the problem, for us and I suspect also for you,
   because you can't have more than one version in a version history have
   the same label.

   So although you could mark one version with the label "author_edgar",
   you could only do that to one version.  I think by the very example you
   chose you want to be need to have custom mutable properties.
