# The objects available via the left-right protocol allow NULL values
# in places we wouldn't otherwise (eg, bpki_cert fields), to support
# existing protocol which allows back-end to build up objects
# gradually. We may want to rethink this eventually, but that yak can
# wait for its shave, particularly since disallowing null should be a
# very simple change given migrations.
#
# At least for the moment, we use trivial custom managers on these
# classes to provide a simple way of looking up objects from lxml
# objects. Rethink this later if it proves tedious.
# "self" was a really bad name for this, but we weren't using Python
# when we named it. Perhaps "Tenant" would be a better name? Even
# means sort of the right thing, well, in French anyway.
# Eventually rename in left-right too, I guess.
