kind=safety | mandatory (kind of decompression stop, whether safety stop, or mandatory decompression stop) — compulsory
decodepth=depth of decompression stop given in metres as a real number — compulsory
duration=duration of decompression stop given in seconds as a real number — compulsory
Via <decostop> a decompression stop calculated by a dive computer, or a dive simulation program respectively, is indicated. While on dive computers normally only the deepest deco stop is displayed (although all shallower deco stops are also known at this time), UDDF allows to indicate all these necessary decompression stops at a <waypoint>. Then several <decostop> elements follow one after the other.
A <decostop> always consists of its decodepth, the duration, and the kind (safety stop, or mandatory decompression stop), which must be given as attributes.
