I think I disagree (but I'm not quite sure ;-) . Reading RFC6763 Section 6, I read: "Note that this requirement for a mandatory TXT record applies exclusively to DNS-SD service advertising, i.e., services advertised using the PTR+SRV+TXT convention specified in this document. It is not a requirement of SRV records in general. The DNS SRV record datatype [RFC2782] may still be used in other contexts without any requirement for accompanying PTR and TXT records." As defined in the draft, the service name is NOT registered for DNS-SD and makes no use of accompanying PTR and TXT records. It is defined following RFC2782, defining a "Name" in that RFCs notion and if anything has an accompanying NAPTR. Please advise if you still insist on the definiton of a TXT. > The authors should submit a template at http://www.iana.org/form/ports-services for early allocation and put the Internet Draft as a reference according to RFC6335 as stated in section 8.1.1 of that document. Will do. I've submitted the two forms without a TXT now, hoping that IANA's answer to the above is "TXT is not required". I believe the other four issues do not require intervention by the authors; these are between IANA and the experts. If I'm wrong, please let me know.
