I think  is the most useful, and most consistent with both the nova and
all neutron resources:
Another advantage of this "transparent" passthrough of the data returned by
the client is folks have a workaround in the event heat attributes schema
lack some new value that the client returns. Obviously when it's added
to the attributes schema, it'll be better to use that instead.
