DDSSEC13 — The DDS-Security specification makes some modifications to the DDSI-RTPS protocol that should be taken into consideration

The following two sections in DDS-Security 1.1 affect future versions of DDSI-RTPS.

The DDSI-RTPS should include language that makes sure future versions do not conflict with what DDS-Security and future revisions thereof may do.

Specifically the following two sections of DDS-Security 1.1 should be taken into consideration

7.3.6.1 Change to the RTPS minor version number
Implementations of this specification shall set the RTPS protocol version number present in the RTPS Header. The RTPS Major version number shall be set to 2 and the RTPS Minor version number shall be set to 3. Future revisions of the DDS-RTPS specification shall take into consideration this fact.

7.4.1.3 Reserved RTPS parameter IDs
This specification reserves the RTPS Simple Discovery Protocol ParameterIDs in the range:
0x1000 to 0x1FFF and 0x5000 to 0x5FFF. The second interval covers the same range of parametersID, except they have the must-understand bit set. This reserved range applies to RTPS version 2.3 (see 7.3.6.1) and higher minor revisions of RTPS. Future revisions of the DDS-RTPS specification shall take into consideration this fact.
