Which would be great if we had sessions and a base level initRequest over
which to negotiate ;) But I take it that you'd thus rather have 1.0
clients talking successfully to 1.1 servers.
Just so I'm clear about what our XML would look like:
<srw10:searchRetrieveRequest
xmlns:srw10="http://www.loc.gov/zing/srw/v1.0/"
xmlns:srw11="http://www.loc.gov/zing/srw/v1.1/">
<srw10:query>ccg.title = sword</srw10:query>
<srw11:resultSetTTL>600</srw11:resultSetTTL>
<srw10:startRecord>1</srw10:startRecord>
<srw10:maximumRecords>5</srw10:maximumRecords>
<srw11:recordPacking>xml</srw11:recordPacking>
<srw10:recordSchema>http://srw.o-r-g.org/schemas/ccg/1.0</srw10:recordSchema>
<srw11:recordXPath>/card/name | /card/type | /card/artist</srw:recordXPath>
</srw10:searchRetrieveRequest>
Yes?
What about SRU, which doesn't have any convenient place to put this
information? It's just out of luck? Or we're going to put in a new
'&version=1.1' parameter?
