In line with comments I've made in other threads I think it makes sense for us to limit link relation discussions to the generic relation itself rather than any specific implementation of it.
Several relations would need a similar treatment.
For example:
edit: An IRI of an editable Member Entry. When appearing within an atom:entry, the href IRI can be used to retrieve, update and delete the Resource represented by that Entry.
BTW, what would be the generic link relation to indicate an AtomPub collection (only the service document is registered at IANA) ?
