Subject: OpenSearch relationship to Search-WS

Presently, I am not yet getting the relationship between Appendix D and 
the rest of the spec. It is either not obvious or perhaps it is work 
that remains to be done.

As I understand things, Cql expressions are the central thing in 
performing a search operation in a serach engine that implements 
Search-WS interface.

A key info I am missing is how does an opensearch client use open search 
interface to
issue a Cql query? What is the use model for such an opensearch client?

Although I like opensearch, I am concerned about an OASIS spec having a 
normative dependency on a spec that is not even on a standards-track. I 
can see that we are copying OpenSearch spec content into our spec to 
work around this. This seems very inadvisable.

An alternative way to deal with opensearch would to:

    * Make Appendix D Informative / Non-normative.
    * Remove the duplication of opensearch content from Appendix D and
      just reference:
      <http://www.opensearch.org/Specifications/OpenSearch/1.1>
    * Add content that describes:
          o How a Search-WS server *MAY* implement support for
            OpenSearch based search clients
          o How an OpenSearch Client *MAY* search a Search-WS server
            using opensearch

BTW, FWIW, I am trying to deal with the same issue (how to support 
opensearch) in RegRep 4.0, OGC Catalog, OGC Web Registry Service specs 
and that is the direction I am leaning towards at present. I would like 
to understand the rationale for the approach taken in Search-WS. 
Ideally, these various specs should address the opensearch issue in a 
consistent manner.
