This was my original proposal, but I have changed my mind, as the most common ways to do this, seems to be rendering either territorial waters or baseline/internal waters with countries on both sides. OK, so proposal 3 is not perfect for all renderers, but it is a pretty good start for the most common rendering needs, and it reflects the legal situation for these borders pretty well. It also is a good starting point for fiddling in the database to get other rendering rules. I have asked if you can come up with a rendering rules for your proposal (which is still not documented in the wiki) for the most common ways to render maps. I will provide some for proposal 3 as sson as I have the time. > Maybe boundary=somewhat_important?

So it should be boundary=administrative. > If you want to, you can add extra tags as hints to renderers. No, they are not administrative borders "like all the others". They are part of a hiearchy, where territorial waters is the most important. Please take another look at http://en.wikipedia.org/wiki/United_Nations_Convention_on_the_Law_of_the_Sea How should internal waters, contigious zone and EEZ be tagged? They are also boundaries. - Gustav
