3.5 Identity Constructs
An Identity construct is an element whose content conveys a permanent, universally unique identifier for the resource (instantiated|described) by the construct's parent element. An Atom Document MAY contain multiple (revisions|versions) of the same resource, in which case the content of the Identity construct for each would be identical. Applications MAY decline to display more than one version of each resource.
Comments? Preferences? Better ideas? Is it ready for a Pace?
It doesn't make a bit of sense unless you define "entry" and "feed", as has been pointed out numerous times over the past few days. This text is defining a feed in the text on atom:id, which should be short.
If you define feed as a "sliding window on a stream of entries", your definition makes sense. If you define feed as a "server-determined representation of the current status of a set of entries", then it only makes sense to include one entry per atom:id. I would argue the second definition makes a lot more sense and accurately reflects real-world usage, where even the RDF formats recommend against repeating rdf:about.
