org.openbp.core.model.item.process.NodeSocket
A node socket constitutes an entry or an exit of a node. The node parameter contains the same data as an activity parameter, but may have a control link connected to it. The socket may have a number of parameters.
An exit socket can be designated as default socket. If the node is not implemented yet, the engine will use this socket as output path of the node. @author Heiko Erhardt
