Thanks! Yes, I agree. Although the main goal of the document is
to describe a steady state configuration involving multiple signing
operators, the key management methods described can also aid
non-disruptive transfer of operation from one provider to another. I
already had on my TODO list to eventually add a section on provider
migration, but I haven't gotten there yet.

Regarding EPP, a zone owner deploying one of the multi provider
models may have to use EPP for bootstrapping the DS RRset contents,
if  the zone in question is an SLD and they are under a TLD that uses
or requires it. But as you say, not all TLDs use EPP, and the document
doesn't express a point of view or requirement on this topic.

For the managed DNS providers themselves, we simply say that they
need to provide some sort of API for ZSK or DNSKEY import. In theory
that could be EPP, but more commonly is some sort of REST/Web based
API. It could also be UPDATE I suppose if they supported it.

Shumon.
