Yup, that's what this is for

Link: </.wac/everyone.n3>;
  rel="http://www.w3.org/ns/auth/acl#accessControl";;
  title="Access Control File"

as per http://tools.ietf.org/html/draft-nottingham-http-link-header-10#section-4.2

'Applications that don't wish to register a relation type can use an
   extension relation type, which is a URI'

Even if a WAC link relation value was registered, it'd have to state to expect some form of RDF ACF in response else problems would arise, hence creation of the aforementioned^^ :)

rel=meta is insufficient.

rel=http://www.w3.org/ns/auth/acl#accessControl is better.

better still would be a registered link relation value [1] (e.g. "WAC").

ACL Ontology has been updated, thus we now have:

http://www.w3.org/ns/auth/acl#accessControl
  'The Access Control file for this information resource.
   This may of course be a virtual resource implemented by the access
   control system. Note also HTTP's header  Link:  foo.meta ;rel=meta
   can be used for this.'

Nathan,

That sort of reminds me of something [1] ;)

So, I asked a round a bit [2] and the answer essentially was: go register
one ... fancy doing it together?
The latest document draft-nottingham is here btw

  http://cidr-report.org/ietf/idref/draft-nottingham-http-link-header/

One could just register it by adding the relation in the acl ontology such as

acl:rules a rdf:Property;
   rdf:domain foaf:Document;
   rdf:range foaf:Document;
   ...

As you can see in the 5.5 examples, you can have a rel value as a URL. ( So in 
this it is similar to
atom). The only disadvantage then is that you don't get the nice shorthand, for 
inclusion in Atom XML,
and other documents.
Yup that's what I went for too :)
