Issue
One paragraph summary of the issue and the solution as detailed in this proposal.
Recommendation(s)
- Add a new (optional) attribute in the queryAck and queryContinuation classes, called "continuationToken", of datatype ST.
- Description of queryAck.continuationToken: Contains the the continuation state (the state of the query server, e.g. the relational database id of the last "record" returned). If queryAck.continuationToken is valued by the query server the querying system SHALL populate queryContinuation.continuationToken with that value in any subsequent query continuation/cancel interactions.
- Description of queryContinuation.continuationToken: Contains the continuationToken which contains the continuation state as reported by a stateless server. If a responding system values querAck.continuationToken, a querying system SHALL populate queryContinuation.continuationToken in subsequent query continuation/cancel interactions with that value.
