The simplicity comes from being able to control the returned contents by
specifying a responseSchema. Not only does this simplify the interface, but
it also simplifies the Explain mechanism.
Maybe I have missed a point though. I don't understand why there is a
schema for SRW at all. We shouldn't be returning an XML record described by
a schema. We should be returning a searchResponse object encoded and
decoded by the SOAP toolkits who create a schema-less (well, SOAP schema)
XML record. I don't want to get a string as a response that I have to
parse. That's why we chose SOAP. Otherwise, we might as well make up our
own protocol and skip the SOAP overhead.
