Dynamic attribute links

[msher]

I am looking for a way to provide a documented link between two attributes (in the same or different class).
Currently I am using tagged values for that.
This approach breaks as soon as the referenced attribute or class are moved or renamed.
Is there a way to avoid that?

Ideally I'd look for a predefined tag type, which would provide for a type dropdown list followed by attribute/method dropdown list to produce the tag value. This value would then mutate as the referenced class/attribute are moved/renamed.

I'd be happy to use some other methods (not tagged values) if such are available.
