/**
* <p>
* <b>Purpose</b>: Define interface for sequencing server.
* <p>
* <b>Description</b>: This interface accessed through
* ServerSession.getSequencingServer() method.
* Used for creation of ClientSessionSequencing object
* and for access to sequencing connection pool.
* Note that if session is disconnected ServerSession.getSequencingServer() always returns null.
* Setup of SequencingConnectionPool is done only through SequencingControl interface.
* Even if getSequencingControl().setShouldUseSeparateConnection(true) is specified,
* SequencingConnectionPool is NOT created unless the session has at least one Sequence object
* that requires transaction.
* <p>
* <b>Responsibilities</b>:
* <ul>
* <li> Connects sequencing on ClientSession with sequencing on ServerSession.
* </ul>
* @see ClientSessionSequencing
