Subject: [armd] What is the proper definition for Broadcast Domain? which is used in draft-ietf-armd-problem-statement-00

draft-ietf-armd-problem-statement-00 has the following definition for Broadcast Domain:

Broadcast Domain: The set of all links and switches that are
traversed in order to reach all nodes that are members of a given
L2 domain. For example, when sending a broadcast packet on a
VLAN, the domain would include all the links and switches that the
packet traverses when broadcast traffic is sent.

The phrase of "are members of a given L2 domain" is a bit confusing because L2 domain could have up to 4095 VLANS, with each one being its own broadcast domain.

Therefore, I think it is more accurate to say "The set of all links and switches that are traversed in order to reach all nodes that are members of a given VLAN of a L2 domain."

Any other suggestions?
