[rbridge] Final outcome of outer VLAN tags on RBridge-RBridge packets?

I'm not sure I understood the final consensus on what we should do for
outer VLAN tags on inter-RBridge packets.
The possibilities I think the consensus might have been are:
a) only use VLAN 1, explicit tag, no configuration possible.
b) default is VLAN 1, explicit tag, configuration is possible to change
sending with VLAN tag(s)
something other than 1. If this is what was decided, I don't believe
we've worked out the design
details. I'd assume this would mean RBridges should be willing to
receive packets from other
RBridges regardless of outer VLAN tag. Would we then mark in the Hellos
what VLAN tag(s)
you've heard from what other RBridges with? What do we do with multicast
if there isn't a single
VLAN tag that seems to work to send to everyone? Would we allow
send on a set of VLAN tags, or just on one at a time (and we allow
configuration to say
which one it is)?
Certainly a) is simpler. If the consensus was b), we'd better work out
