XTCE12 — Improve CRCType Polynomial element

  • Key: XTCE12-12
  • Legacy Issue Number: 19436
  • Status: closed  
  • Source: NASA ( Mr. James Kevin Rice)
  • Summary:

    The annotation states that the coefficients of the CRC poly can only be 1 or 0, and the exponent can only be integers. However the schema types for these two attribute are double. Enforcing the annotation through changes to the syntax of its polynomial would be easy to accomplish. A new type for CRC polynomials would need to be created, and the attribute types changes to match the desired behavior.

  • Disposition Summary:

    Updated in previous issue resolution, not known which

    Create a CRCPolynomialType in the schema that only allows 0 or 1 for the coefficients and non-negative integers for the exponent and use it instead of the sequence of Polynomial elements.
