SYSML2 — Add a distinguished attribute to capture the textual body of a requirement

  • Key: SYSML2-546
  • Status: open  
  • Source: INCOSE ( Mr. Sanford A. Friedenthal)
  • Summary:

    A requirement should include a text body to capture the shall statement or other human readable requirement statement. The doc annotating element is one way to accomplish this. However, a doc element on a requirement definition is inherited by its requirement usages, but it cannot be redefined on its usage. (Note: The texts of a RequirementUsage are the bodies of the documentation of the RequirementUsage.)

    The proposal is to add a distinguished attribute to capture the text body of a requirement that would replace the derived text attribute/documentation. This distinguished attribute can be redefined. This avoids a requirement usage from having both the original text in the requirement definition and the modified text in the usage.

    The concrete syntax should be updated accordingly.
