Looking at the diagram at...
https://www.ngsgenealogy.org/ngsgentech/projects/Gdm/Diagram_GENTECH_Data_Model_1.0.pdf
...., it looks like ASSERTION.Value is there to hold a pointer to either
an Event-Type-Role-ID or a Group-Type-Role-ID (what the model calls a
"value connection"). So it sounds to me that it could very well be an
unused attribute when in the context of a CHARACTERISTIC.
Characteristics that consist of multiple parts (like names) can be
assembled using CHARACTERISTIC-PART.Sequence-Number, right?
Thanks for your comments,
