SDMN — ReferenceConnector for DataItems does not match the semantics of ItemDefinition reference relationships

For ItemDefinitions, the reference relationship affects the content (structure) of the source ItemDefinition. For DataItems, the ReferenceConnector does not affect the structure of the source DataItem. The proposal for the graphical elements for ItemDefinition modeling plans on re-using the ReferenceConnector line. Thus, there is a conflict.
Either the ItemDefinition should use a different line style or the ReferenceConnector should be redefined.
However, based on an analysis of the definition of the ReferenceConnector it could be argued that the basic Association connector (inherited from SCE) provides the same semantic capability. Thus, the ReferenceConnector would be better to be redefined to match the semantics of the ItemDefinition reference relationship.
