SYSML2 — Limitation on specifying view renderings

  • Key: SYSML2-155
  • Status: open  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    In 7.25.2 View Definitions and Usages, the third paragraph includes the parenthetical comment:

    (Note that, in the textual notation, it is only possible to specify a view rendering using reference subsetting.)

    This correctly reflects the following textual notation BNF in View Definitions:

    ViewRenderingMember : ViewRenderingMembership =
        MemberPrefix 'render'
        ownedRelatedElement += ViewRenderingUsage
    ViewRenderingUsage : RenderingUsage =
        ownedRelationship += OwnedReferenceSubsetting

    However, neither the abstract syntax (see 8.3.25) nor the semantics (see 8.4.21) of view rendering require this restriction. The textual notation should be updated to allow a more general declaration of a view rendering usage, consistent with what is representable in the abstract syntax.
