SYSML2_ — Issues with the 'Swimlane' Element Specification

The Swimlane element is described in the specification as containing two elements: Usage-name-compartment and action-flow-node. However, several issues arise with this definition:
The issues regarding the Swimlane:

1. The Usage-name-compartment is not specified.
   • The specification does not provide any details or clarification for the Usage-name-compartment element, leaving its definition ambiguous.
2. Incomplete action-flow-node Definition
   • The definition of action-flow-node excludes relationships and action usages.
   • It currently includes only the following:

     action-flow-node =
      start-node
      | done-node
      | fork-node
      | join-node
      | decision-node
      | merge-node
      | send-action-node
      | accept-action-node
      | while-loop-action-node
      | for-loop-action-node
      | if-else-action-node
      | assign-action-node

   • Examples in Table 14. Actions - Representative Notation display a compartment named perform actions within the Swimlane.
   • The specification, however, does not declare that such a compartment can be displayed, leading to inconsistency
