XML namespace clarification

[Oliver Schonefeld <schonefeld@ids-mannheim.de>]

Hello search-ws-comment,

I'm trying to implement SRU 2.0 and am a little confused about the XML 
namespaces. I've downloaded the v1.0 specification documents from the 
OASIS website therefore I assume those are the effective specification 
documents.

The example in section 4.4 "Example Scan Response" of Part 6 (Scan) has 
"http://docs.oasis-open.org/ns/search-ws/sru-2-0-response"; for the XML 
namespace, while section 1.3 "Namespaces" of Part 0 (Overview) states 
that the namespace is supposed to be 
"http://docs.oasis-open.org/ns/search-ws/sruRequest";. The XML schema 
also has "http://docs.oasis-open.org/ns/search-ws/sruResponse";.
Am I correct to assume that the namespace in example in Part 6 is is a 
typo and the correct one is the one from overview in Part 0?

A similar issue exists in section 11.3.1 "Non-Surrogate Example" of Part 
3 (SRU 2.0) line 619: the example uses 
"info:srw/xmlns/1/sru-2-0-diagnostic", but Part 0 (Overview) states 
"http://docs.oasis-open.org/ns/search-ws/diagnostic";.
Another one exists in section 14 "Echoed Request" of Part 3 (SRU 2.0) in 
line 837: the example has "info:srw/xmlns/1/xcql-2-0-v1" for the XML 
namespace of xcql, while section 1.3 "Namespaces" of Part 0 (Overview) 
states "http://docs.oasis-open.org/ns/search-ws/xcql";.

A different issue exists with Part 2 (SRU 1.2) of the spec: section 1.3 
"Namespace" states "All XML namespaces for the set of documents in this 
collection are supplied in the Overview document: searchRetrieve: Part 
0. Overview Version 1.0", thus e.g. the namespace for the sruResponse 
should be ""http://docs.oasis-open.org/ns/search-ws/sruRequest";.
However, this would break backward-compatibility with exiting servcies, 
because the XML schemas that where published on the LOC website[1] for 
SRU 1.0. E.g. it had "http://www.loc.gov/zing/srw/"; for the target 
namespace for the SRU response.
Which namespaces shall a service that aims to implement SRU 1.2 use?

Thank you and best regards,
  Oliver
