Create a link so that feeds can point to their service document(s).
Currently there is no standard way to find a service document. There is a well understood ways for finding atom feeds from html pages, using a link relation. Atom xml aware processors are much more likely to be also atom APP processors than plain html/xhtml processors are, so it makes sense to place this information in a feed so that once this feed is found the service document can easily be found too.
add the following
[[ 11.3 The "service" Link Relation
This specification adds the value "service" to the Atom Registry of Link Relations (see section 7.1 of [RFC4287]). The value of "service" specifies that the value of the href attribute is a service document somehow related to the containing element. The "type" attribute for a link relation is understood to be 'application/atomserv+xml' if not specified.
None. Should make it easier to find service documents, when implemented.
