optional, multiple


ref=unique identifier of the tank whose pressure is indicated (optional)


More and more dive computers are "air integrated" and show the tank pressure permanently during the dive. Via <tankpressure> it is indicated at a <waypoint>. In particular with so-called "technical diving" several tanks are used which normaly contain different breathing gases. Then several tank pressures are shown by the dive computer, too. Therefore the attribute given with <tankpressure> indicates that tank the pressure value belongs to. In case there is only one tank, or a linked double-tank with only one pressure value measured, the attribute may be omitted.
