SYSML21 — Need to enable nested swimlanes in graphical BNF

Open Closed All
  • Key: SYSML21-358
  • Status: open

  • Summary:

    Currently the graphical BNF only allows a flat sequence of swimlanes.
    However in case of a hierarchical parts structure, for example, it is desired to represent the parts containment hierarchy using a hierarchy of nested swimlanes. For example a swimlane that represents a vehicle is partitioned into two nested swimlanes for the engine and the transmission.
