Oh, man. I used to work at Lonely Planet a few years ago. This sort of thing came up all the time. Depending upon jurisdiction, there are even legal requirements about where borders lie, what you call different territories, etc. And of course these requirements vary between jurisdictions. So a map that you can put in a book to sell in country X will have to be replaced with a different map in order to sell in country Y. The Persian Gulf is the example that springs to mind, but IIRC there were many others too.
