When I said removing Section 6, I meant the couple of leading
paragraphs in the section before Section 6.1, i.e.,

from

   Note:  This non-normative section gives some hints for implementing
      the processing of the RDNSS and DNSSL options in an IPv6 host.

to

   [...]  Whenever there is an expired entry in the DNS Repository, the
   daemon can delete the corresponding entry from the Resolver
   Repository.

I didn't mean removing Section 6.x, and I'm not even sure if it's a
good idea.  We'd certainly revise the first sentence of Section 6.1:

   For DNS repository management, the kernel or user-space process
   (depending on where RAs are processed) should maintain two data
   structures: (i) DNS Server List that keeps the list of RDNSS

so it will be independent from kernel vs user-space considerations,
but the rest of this section rather seems to be describing the general
protocol handling using some conceptual data structures.  They don't
necessarily have to be removed in the context of this discussion, and
I guess they can actually be an important part of this document.
