/** <p>The ConnectionRequestInfo interface enables a resource adapter to
* pass its own request specific data structure across the connection
* request flow. A resource adapter extends the empty interface to
* supports its own data structures for connection request.
*
* <p>A typical use allows a resource adapter to handle
* application component specified per-connection request properties
* (example - client ID, language). The application server passes these
* properties back across to match/createManagedConnection calls on
* the resource adapter. These properties remain opaque to the
* application server during the connection request flow.

* <p>Once the ConnectionRequestInfo reaches match/createManagedConnection
* methods on the ManagedConnectionFactory instance, resource adapter
* uses this additional per-request information to do connection
* creation and matching.
