DDSXTY14 — Extra text left in section Member IDs

  • Key: DDSXTY14-8
  • Status: open  
  • Source: Real-Time Innovations ( Dr. Gerardo Pardo-Castellote, Ph.D.)
  • Summary:

    In DDS-XTYPES 1.3 there was an issue ( whose resolution added the precise specification of the computation of the memberId. This is now in section 'Member IDs' specifically the three-step algorithm towards the end of the section.

    This algorithm fully uses 32 bits. The 4 MSB are set to zero and the remaining 28 bits computed from a hash. Because of this there is no longer a 'reserved range' for memberIds.

    However the resolution of DDSXTY13-2 still left some text in section that talks about reserved ranges. This text should also have been removed. In fact it seems that there was an instruction in DDSXTY13-2 to remove the paragraph but it either was not applied correctly or it missed a sentence that followed the paragraph. To correct it, the following text should be removed from section 'Member IDs'

    The remaining part of the member ID range—from 0 to 268,402,687 (0x0FFFBFFF)—is available for use by application-defined types compliant with this specification.
