FYI.. the "service" link rel has been added to the IANA registry.

Short version: rel="service" indicates a URI that can be used to
retrieve an Atom Publishing Protocol Service Document as defined
by RFC 5023.

You may have seen
[1] http://www.w3.org/2001/tag/doc/selfDescribingDocuments-2008-05-12.html#ATOM

In the example above, the short name "enclosure" is used.

I was surprised to get a 404 error on
http://www.iana.org/assignments/relation/enclosure

Likewise,
http://www.iana.org/assignments/relation/service
also results in 404.

RFC 4287 section 4.2.7.2 specifies [2] as a base.
[2] http://www.iana.org/assignments/relation/

Looking at
[3] http://www.iana.org/assignments/link-relations.html

Some of the values for @rel can be resolved using the following base URI
[4] http://www.iana.org/assignments/link-relations/

However, even using this base others give a 404 error.

Is there errata or some other RFC that specifies [4] instead of [2] as the base?

A "good practice" stated in [1] is that
"Web representations should link to the information needed to support automatic processing of those representations. "

So either the value of @rel is a URI/IRI, or it is a short form with a well specified way to construct a URI/IRI.
Given that URI/IRI, it should be resolvable.

Are there any plans to provide a document that can be resolved for every @rel value registered with IANA [3]?

I've mentioned some of this to W3C TAG
