ulex:TimeoutDuration

A time in seconds within which the requesting system would like to receive a response. This element would primarily be used to convey a time period past which a response would not be useable by the requesting system. The time period specified excludes time for connection overhead to avoid the need for time synchronization between systems and thus should be slightly shorter than the period needed by the requesting system. The server, if capable of supporting such functionality, should cancel the search and return a timeout advisory response within the time limit specified. It is suggested that the search query should be timed out by the server prior to the time limit specified in order to allow time for canceling the query and returning a response before the period expires.
