Thanks for the feedback. I'm actually asking a stupider question than you
think.

I saw the reference to [6] in RFC 7561, but I was scanning for "GSMA", and
the only occurrence to that string that I saw was in the Informative
References section.

   [6]  3GPP, "Guidelines for IPX Provider networks (Previously
        Inter-Service Provider IP Backbone Guidelines)", GSMA Official
        Document IR.34 v11.0, November 2014,
        <http://www.gsma.com/newsroom/wp-content/uploads/
        IR.34-v11.0.pdf>.

If a reader is persistent enough to click through the references in an RFC
that's listed as a reference, the reader can figure this out, but it isn't
obvious.

So I think I'm asking if you can add [6] as a reference in your draft,
perhaps pointing to

   There is also a recommendation from the Global System for Mobile
   Communications Association (GSMA),

You'll know best where to point it, of course, but I'd like to point to the
actual GSMA recommendation if we're going to say

   This GSMA specification was developed
    without reference to existing IETF specifications for various
    services, referenced in Section 1.1.

which seemed to refer back to *RFC 7561* as the GSMA recommendation, which
is what confused me in the first place :-)

Spencer, who is noting with bemusement that neither TSV AD balloted on RFC
7561 when it was approved ... how did we miss THAT one???
