My understanding is that SRU is a _protocol_, not a media type? SRU is a messaging protocol just like SOAP and HTTP. When SRU and SOAP are tunneled through HTTP you are sending back the SRU "message" as the HTTP entity representation which contains a result set from the search. You can register protocol messages with IANA, e.g., application/soap+xml and message/http. Andy.
