Except that you don't let the reader know what the LMA FQDNs via SRV [RFC2782] query is? If you did (maybe in Section 3.3) the case would be closed on DNS discovery.

Give the QNAME in Section 3.3 that will be it. I think that the document can stay as informational. In Section 3.3, you mention APN as service name for LMA. This contradicts with your v6ops draft which says APN is used to identify P-GW for a (GTP) MN. Not all P-GW's could be LMAs. In Section 3.3 you mention names agreed on among operators that belong to the same inter-operator roaming consortium like 3gpp-pgw:x-s8-pmip S-NAPRT app-service/protocol. This seems to be PMIPv6 related because it has pmip but I think such names are out of scope for your draft, they address different needs. So my conclusion is that Sec. 3.3 on service names fails short of coming up with one and yet it is somehow assumed in Section 4 2nd paragraph. What a mystery. Cheers, Behcet
