In JSOM you can create a way from segments which are not adjacent to each other. Is this correct to do so?
Why I am asking:
When creating highways or waterways there often are short way elements (most of the time only a single segment long) which require special tags. (layer=-1 or bridge=yes …)
May the two parts of the way before and after this short segment belong to the same way element (normally they need the same tags) and only the segment in between gets its own way element with the special tags. Or must there be two distinct ways before and after? (This would mean that whenever a way crosses another way above or below, this way has to be split in 3 ways.)
Another question I have is if it is OK to asign a “layer=-1” tag on a small river over a longer distance, because it crosses under several streets.
