To tell the truth, I do not completely understand the protocol, or the
problem it tries to solve. But I work on that. A high-level
description would help. Section 2 is quite confusing. It says "The
DNS client may obtain the contextual resolving domains via various
way, including a configuration or via DHCP Options [I-D.btw-add-home]"
and later "This document describes two mechanisms for a DNS client to
retrieve resolving domains", these mechanisms being different from the
ones mentioned in the first sentence.

First question, about the concept of "resolving domain". 5.1 says
"FQDN - such as resolver.example.com - and the domain part (
example.com ) is designated as the resolving domain". The term "the
domain part" is unclear. Does it mean "the FQDN without the
most-specific label"? If the resolving service is
foo.bar.example.eu.org, is the resolving domain bar.example.eu.org?
(5.3 seems to imply this.)

Second, I do not get the relationship between "resolving domain" and
"resolving domain list". What is called "resolving domain" in 5.1
seems to be a "resolving domain list" in 5.2.
