The purpose of the document is to convey technically how PSD DMARC can be
accomplished rather than who can or cannot undertake this due to policy
considerations. As the operator of .BANK and .INSURANCE, fTLD initiated
this stream of work with the IEFT because of the explicit prohibition by
ICANN from inserting TXT records in the DNS. The goal is to get to an RFC
that specifies the technical aspect of PSD DMARC and ultimately seek
ICANN's approval to allow publication of such a record in the DNS. In
contrast, gTLDs not under contract with ICANN such as .MIL and .GOV, who
are both involved in this work, do not have a contractual relationship with
ICANN and thus are not prohibited from this activity, and the same goes for
ccTLDs.
