Actually, the PSHB use case *was* frequently discussed in the Atom WG... The
reason for this is that what PSHB does is provide pretty much what FeedMesh
was intended to provide - a topic based subset of the content-based system
that Pubsub.com provided.
An atom:source, if present in an entry, should never be modified or
overwritten by an aggregator. An aggregator should only add atom:source if
it isn't already present.
If you want to show provenence, you need to add an extension element. As
pointed out in an earlier message, the WG was aware that provenence was
useful but we couldn't get consensus on how to record it.
Please, if you define a provenence element, include in the definition a
requirement to remove that element prior to canonicalisation when verifying
signatures...

Agreed to keeping the tone civil -- assume good intentions until proven

Mea culpa for not noticing this issue with PubSubHubbub.  The Atom spec
didn't envision this use case and so atom:source is almost, but not quite,
what's needed -- thus the confusion is understandable.

The right thing to do IMHO is to add something like a psh:provenance element
that is just like atom:source but tracks the most recent context of the
entry.
