GEMS14 — "Range of Values" specified for "Message Length" is incorrect

  • Key: GEMS14-23
  • Legacy Issue Number: 19739
  • Status: closed  
  • Source: Anonymous
  • Summary:

    In Table 8.2
    "Message Length" has a "Range of Values" specified as "000074-999999". We took this as the minimum possible message length to the maximum possible message length. Which, given our experience, is not true. We have encountered several instances with production hardware (Amergint & RTLogic) where the message length was fewer than 74 bytes.

    I personally don’t care if OMG decides to list a minimum length; I just want the documented "Range of Values" to reflect reality. In the case OMG doesn’t want to specify a minimum length I would suggest the range value would be listed as "000000-999999" in the spec. Listing a range of "000000" could be problematic/confusing as well, "000000" would never be a valid either... So... I will let you standards people work this one out.

    Range of values in the message length

    Change the range of values. Since the standard header may change, it makes sense to not specify the minimum length. That will make maintenance of the specification easier.
