Which element is represented by a dashed boundary rectangle in a system model?

In systems modeling, a dashed boundary rectangle is used to represent a Reference Property. This visual cue indicates that the element is a reference to another defined element, allowing for clear delineation of its boundaries while also signifying that it is not a new or independent property.

The dashed boundary helps distinguish Reference Properties from other elements in a model, making it easier for modelers and stakeholders to understand interdependencies and connections between elements. By using this notation, it visually communicates that the property is a stand-in for another element, rather than a completely new instance.

Additionally, the use of a dashed boundary rectangle supports effective communication within the model, helping various users to interpret the structure and relationships within the system effectively. This understanding is crucial for accurately modeling and analyzing systems as well as for collaborative work among teams.
