In the ER diagram for the full model, should references to identifiers be represented with dashed lines?

[ASL-rmarshall]

When an instance of a class is referenced by identifier (the referenced class is not defined as inlined in the model), instances of the classes at both ends of the relationship can exist independently. This implies that the relationship is "non-identifying", in which case it would be better represented as a dashed line in the ER diagram.

Currently, the ARS ER diagrams are generated by the linkml ER diagram generator, which assumes that all relationships are "identifying".
