Added the following paragraph to OPC UA Part 4 - Services RC 1.04.14 Specification.docx:

Part 6 defines a reverse connect mechanism where the Server initiates the connection by creating a socket. All following steps like creating a SecureChannel are initiated by the Client. In this scenario the Client is only able to initiate a reconnect if the Server provides a new socket after connection interruption. Except for the socket creation, the Client side reconnect handling described in Figure 39 applies also to the reverse connect case. A Server is not able to actively check the connection status. Therefore the Server shall create a new socket in a configurable interval, even if a connection to the Client is established. This ensures that a socket is available for the reconnect handling in addition to other scenarios where the Client needs more than one connection.

Agreed to changes edited in Raleigh meeting.
