Besides, the way I suggested it in Proposal 3 allows for clean and simple tagging, and doesn't make it difficult for rendering software to choose if they want to render maritime borders or not. The point in tagging maritime borders is to give access to the information, and that gives reason to clearly differ between borders at sea and borders at land. Whether there is a difference between them or not is not up to us, but to those who choose to use the data, and that is reason enough to tag them different. Yes it can be done by adding maritime=yes to an administrative border, but I really don't see the point in treating the territorial border differently than baseline, contingency zone, eez, and what other maritime borders that we might decide to enter. If you are not happy with Proposal 3, write your own, you are free to add it to the rest of the proposals on Maritime Borders. -- Brgds Aun Johnsen via Webmail
