I wonder about using the marine types for inland surveying features, in the glorious struggle trading off rendered accuracy and ability to convey as much information as possible. Probably that's something I'll do privately only, as I can see a lot of objections. >> At this time, the various extra attributes that can be assigned to the >> marine entities (depth, colour, light colour/flash, etc.) are not >> handled but I have made some progress in understanding their encoding >> so at least some of these could be supported in the future.

Perhaps all the used features are already there, but it would be nice to keep it updated to at least all the features we use.
