SYSML21 — Inconsistent Usage Representation in Parameters Compartment

Open Closed All
  • Key: SYSML21-333
  • Status: open  
  • Source: Dassault Systemes ( Mr. Tomas Juknevicius)
  • Summary:

    Currently, the usage appearance in the ‘parameters’ compartment is defined in the “8.2.3.17 Actions Graphical Notation” chapter as follows:

    parameters-compartment-element = el-prefix? FeatureDirection UsageDeclaration ValueOrFlowPart? DefinitionBodyItem*

    This is not consistent with other compartments that represent elements which can declare a direction (it includes only the ‘direction’ modifier but omits others), such as items, parts, and attributes:

    items-compartment-element = el-prefix? OccurrenceUsagePrefix usage-cp
    parts-compartment-element = el-prefix? OccurrenceUsagePrefix usage-cp
    attributes-compartment-element = el-prefix? UsagePrefix usage-cp
