6.2. Known Issues with Serialization and Deserialization

6.2.1. Some parameters cannot be received multiple times within same SPDP sample

The OMG Real-Time Publish-Subscribe (RTPS) specification, version 2.5 allows in general that “The ParameterList may contain multiple Parameters with the same value for the parameterId.” RTI Connext, however, does not support receiving the following parameterId values multiple times within the same Simple Participant Discovery Protocol (SPDP) discovery sample:

• PID_USER_DATA

• PID_PROPERTY_LIST

• PID_ENTITY_NAME

• PID_ROLE_NAME

• PID_PARTITION

• PID_DOMAIN_TAG

• PID_IDENTITY_TOKEN

• PID_PERMISSIONS_TOKEN

• PID_TRANSPORT_INFO_LIST
