Sorry I forgot the image. Here it is:
> The idea itself is good, it could secure more consistent tagging and
> easier automatic processing of data.
> In the proposal it says:
> "If you have one way making up the line string ring and it does not
> describe something in its own right, you may also put these tags on
> the relation and leave the relation untagged." - that does not really
> make sense to create such relation (one way tagged relation would make
> splitting the way easier).
> "The order of the relation members does not matter (but properly
> sorted member lists can help human editors to verify completeness)." -
> I believe it should be always sorted, yet routers/renderers should not
> rely on it.
> How would it be used in this situation?: border of two countries (A,
> B) is also border of lower administrative divisions (AC, AD in country
> A and BE,BF in country B). going along the border you go through
> different combinations (A-B all the way; AC-BE->AD-BE->AD-BF; see
> image). In reality there would be more than two levels and therefore
> much more combinations.
> How would it solve the case of river bifurcation if the river merges
> together (river island, the same river flows on both sides)?
> How would it solve similar case of streets (lanes for different
> directions split for some time and later merge together)?
> Thanks for answering these questions
