This is exactly the point what I wanted to touch and consult how we can
define the best generic way. Then documenting it and putting into
practice in these countries.
I would like to recap:
* The tag landmark is not suitable for all possible reference points
* A new tag would be a good option
addr:reference_point=* or reference_point=*
What could be the right values? true, yes, popular, confirmed,...? Any

This goes way to far and, in my opinion, is too complex for considering
it for mapping. I don't think it is necessary (or even possible) to use
exact addresses. Having at least reference points marked in a way
computers can process them would be a big improvement. Let's stick to that.
Thank you for all your responses.
