Issue 17297: Extended parameters should be aligned the same as non-extended ones (dds-xtypes-ftf)
Source: DECA (Mr. Rick Warren, )
Nature: Uncategorized Issue
Severity: 
Summary: Found by: Fernando Crespo, RTI (fernando@rti.com)
Severity: Support Text


Problem:
The section on the parameterized CDR Data Representation (DDS-XTypes 7.4.1.2) contains a reference to the DDS-RTPS specification for the definition of the parameter list data structure. However, it does not specifically refer to the instructions in DDS-RTPS on how to handle alignment within such a structure. This omission may confuse some implementers, especially with respect to extended parameters, which should follow the same alignment rules as RTPS-traditional "short" parameters.


Proposed Resolution:
Add the following paragraph to the end of section 7.4.1.2.1, "Interpretation of Parameter ID Values":


    "The alignment rules for extended parameters shall be the same as
    those for non-extended parameters, which are defined in [RTPS]
    Section 9.4.2.11."
