I think there's some confusion about the id element.

First, it is not a pointer to a static object.  Remember, it is an
identifier for a blog feed, which is not static.  If I fetch that same
blog feed a week later, it will still have the same ID, but will have
new content.  You need to understand the purpose of the id field.  It is
to allow a blog reader to recognize a blog when it comes from a
different source.  The intent is to support movable blogs.  There is no
equivalent concept in SRU.

The nearest equivalent in SRU is the ability to know what query created
the result set, so that it can be recreated at a later date with any new
records added.  We have that in our SearchRetrieveResponse records in
the EchoedSearchRetrieveRequest element.  When we map our
SearchRetrieveResponse records to Atom Feeds, we can put that echoed
query in the Link element with the "rel" attribute set to "self".  This
tells the reader that this is the URL that generated the response.
