link@rel='self' -- different for /collection/entry and link@rel='edit'?

With the caveat that once you retrieve the representation located at
link@rel='edit' (which would include <app:control />), then *that*
representation's link@rel='self' would reference the location where *that*
representation could be retrieved (that's what the 'self' relationship
means).

Uh oh ... everyone, is this a problem? Are we assuming that an entry
resource's 'self' URI would remain the same for all various representations
(ie. as represented in the collection feed, and the 'edit' representation)?
