I assume you're talking about the discussion of the System ID issue, and
not the TLSP Packet Format described in section 2.3 for carrying IS-IS
packets.  (If you *do* mean TLSP, then I'll probably need some
additional clarification.)

I certainly agree with the sentiment (I don't like duplicating
documentation at all, particularly for this issue), but the existing
notation about MAC addresses (and the lack of them on PPP) was added at
the behest of other reviewers who found that it was confusing to match
up the PPP TRILL draft with the primary TRILL documentation without some
indication that there are differences here.

I find I'm walking a narrow line.  I want to provide a little guidance
so that it's clear what's expected here, but I also want to avoid either
just copying hunks of the TRILL and IS-IS documentation or (worse)
carving out special exceptions.  I probably can't please everyone.
