The PubSubCommunicationLinkConfigurationDataType is used by the EstablishConnections Method and provides the configuration of references between a ConnectionEndpoint and a DataSetReader and/or a DataSetWriter.

NOTE   The PubSub configuration elements, including the DataSetReader and/or DataSetWriter to be used for the ConnectionEndpoints, are created using the PubSubCommunicationConfigurationDataType (see 10.10.3).

The PubSubCommunicationLinkConfigurationDataType is formally defined in Table 140.
