Subject: Re: [search-ws] OASIS/SRU: ATOM/SRU Response Schema
+1 on all points made so clearly below and specially the conclusions. I agree that by adopting ATOM as the default, required canonical response format, we have no loss of functionality and that it is really a minor syntactic change, albeit one that brings many benefits to the final spec.
