In response to the former question - at present ZNG supports both forms
but which form a particular implementation supports is left to that
implementor. I don't think we've discussed in detail conformance levels.

I *do* want to keep the SOAP requests in the spec. as I do see a need
for them if we expand ZNG to cope with non-textual queries (which is an
area I'm particularly active in) or complex queries (as it is
recommended that a URL not exceed 256 characters, although in our
context I think that this is not a major issue).

As regards returning the response as a SOAP request - I personally think
it less complex if the response format is the same regardless of the
request format. In any case the only overhead here is to add the lines

<SOAP-ENV:Envelope xmlns:zng="urn:z3950:zng_prototype1"

to the beginning of the response and


to the end. Which I don't see as a big hurdle!
