I agree that a convention will develop organically, but I would add
that the emergence of that convention will be governed by two things:
who has the bigger market share, and who's first to market. When the
first big project like Zope or Twisted announces that "we will do
annotation interop like so...", everyone else will be pressured to
line up behind them. Until that happens, smaller projects like mine
will either a) not support annotation interop (because there's no
good, obvious solution), or b) pick an interop scheme at random
(again, because there's no good, obvious solution).

Thanks,
