Propono's AtomPub server framework allows an implementation to return only a Location header and so
there is no way to specify both the real URI of a created resource (i.e. an HTML blog page) and the
AtomPub edit URI of the resource. Here's how this should work:
- Location: the "real" URI of the created resource (e.g. a blog permalink). To set this an implementation
must return an alternate link with rel="alt" and the URI.
- Content-Location: the AtomPub edit URI for the resource. To set this an implementation returns an
other link with rel="edit"
