It seems that NotationViewDependentsAdvice is made to delete all
elements constituing a NotationView (fontstyle, bendpoints, etc.)
I traced the execution of my command and this helper is not necessary
because with my code, all notation elements are deleted. The notation
file is correctly modified, but the diagram is not updated for my link1.
Is there a command for updating the diagram that could be added to my
destroy command ?
Or maybe must I customize a specific helper or policy ?
