  So, I've been looking at 3.HEAD and am trying to make sure I understand
what you're suggesting here. I see now that it has made it into trunk.

  The outstanding question is how to have an external_acl helper, assumedly
called by an http_access line, return the annotation to then later be matched
with a "note" acl ? This was the mechanism you were suggesting, correct?

  If you have a quick pointer to the mechanism needed to return a note
from the external_acl helper, that would be appreciated. This would be
the "helper annotations API" you referred to, I presume. Thank you.
