  • Summary:

    Page: 181
    Change: This section under-specifies the key fields for all four data types. The "inherited" DDS structures do not provide a key field that is useful for RTPS because it is vendor-specific. This section should describe what a "key only" (KeyFlag==1) Data Submessage should contain as its payload for both SPDP and for all 3 types of SEDP. Table 9.13 indicates that Built-In Topic Keys can be encoded as a GUID, which has no correspondence to the actual definition of Built-In Topic Keys.

    PID_PARTICIPANT_GUID (for SPDP)
    PID_ENDPOINT_GUID (for SEDP)
