I've not been keeping up with the IETF; is there a document that
describes what looks like a de facto standard of using _pname labels
with TXT RRs that is being followed by at least DMARC and DANE in
*._tcp.example.com, *._smimecert.example.com, and _dmarc.example.com
https://tools.ietf.org/html/rfc6698
https://tools.ietf.org/html/draft-fanf-dane-smtp-04
https://tools.ietf.org/html/draft-hoffman-dane-smime-04
http://www.dmarc.org/draft-dmarc-base-00-02.txt

Is SRV the precedent being followed?
