Could WS-Context from WS-CAF help for these situations?

One could provide a separate web service interface for each record within the database, but it would be a much lighter (and frequently more useful) definition if there was a single web service interface that had some well defined means for indicating what record of the database was the target of the current invocation. WSRP had this type of need and had to define a means that is idiosyncratic to our protocol for passing the stateful reference. Defining a standardized means by which infrastructure can take more of the load for handling such references is one of the outcomes I would like to see from the WSRF effort.
