Re: [OSPF] Benoit Claise's No Objection on draft-ietf-ospf-node-admin-tag-07: (with COMMENT)

Benoit,

My understanding is that "independent characteristics" applies on a
tag-by-tag basis.  I might suggest:

	Each tag carried by the administrative tag TLV SHOULD be used to
	indicate a characteristic of a node that is independent of the
	characteristics indicated by other administrative tags.

Thanks,
