Comment on draft-bless-diffserv-multicast-07

[Russ Housley <housley@vigilsec.com>]

The first paragraph of the Introduction really is poor.  It says:

    This document discusses the problems of IP Multicast use in
    Differentiated Services (DS) networks, expanding on the discussion
    in RFC 2475 ("An Architecture of Differentiated Services"). It also
    suggests possible solutions to these problems, describes a potential
    implementation model, and presents simulation results.

What are "these problems?"  I expected the introduction to list the 
problems for which it proposes solutions.
