The DMN Editor only supports creating Association from a DRG Element to a TextAnnotation. The DMN Specification however provides for the Association to have a direction (either from-DRG-to-TA, or from-TA-to-DRG or both).

When implementing the UI model AssociationDirection was omitted as I thought it's direction could be inferred from the source and target nodes. However this may not be entirely accurate (for the "both" direction). Furthermore the UI currently does not support creating an Association from a TextAnnotation.
