      • What we saw of the “shared aggregation” of CurrentData at the ThresholdProfile was an unintended change when creating the v0.14 of the draft G.8052.1 model. It was probably caused by accidentally moving the mouse over the Aggregation field of the Properties pane and altered the aggregation setting from “none” to “shared”.

        The actual association is like the following in G.8052.1 v0.13 (TD521R1/WP3 Feb. 2020) and also in the base G.8052 since many years ago. It was so at least since v2 of G.8052 (2016).
      • Also, the Navigation is “false” for the Member End “associatedCurrentData”. That means the ThresholdProfileAssociatedToCurrentData association is unidirectional navigable. That is, not bidirectional.
