[Tagging] destination_ref vs. dest_ref vs. destination:ref

[Martin Vonwald]

Hi!

Up to now I usually used the tag destination_ref to specify the ref of
the road where a link-road is heading, in analogy with the destination
key. Now I've seen the key dest_ref in use and also destination:ref.
Of course none is documented in the wiki ;-)

What should we do? I could write a proposal but what for what tag?
