Note attached to connector?

[barny451]

I'm trying to read a diagram using the AI, where the diagram includes a note attached to a composition relationship between two classes.

Scanning through the DiagramObjects, the Note symbol and its corresponding Element come across OK but I can't find out what it is linked to because there isn't a NoteLink for the line joining it to the composition.  For Notes attached to symbols, there is always a NoteLink.

This is sort of reflected in the GUI because I can't select the dashed line joining the note to the composition .

I've looked in CustomProperties of the composition and of the classes it joins, but I can't find anything relevant.

So, does anyone know how to determine the Connector the note is attached to?

TIA
