PartitionDescription
/ConfigRecord/Module/Partitions/Partition/PartitionDescription/Ports/QueuingPort
The QueuingPort element defines the configuration of queuing ports for a partition. A port in a partition must be configured as a partition direct-access port. A port in a partition can only connect to an application port in the application that resides in the same partition.
<PartitionDescription> ... <Ports> ... <QueuingPort Attribute="DIRECT_ACCESS_PORT" MessageSize="1024" Name="input1" QueueLength="10" Protocol="RECEIVER_DISCARD" Direction="SOURCE"/> </Ports> </PartitionDescription>

PSEUDO_PORT: Not supported for partitions.
For a partition, this attribute must be set to either DIRECT_ACCESS_PORT or NULL_PORT. In a deployed system, this value should always be DIRECT_ACCESS_PORT.
