The information put into brackets within <mix> define a breathing gas used. If more than one breathing gas is used, several <mix> sections follow one after the other.
If <gasdefinitions> is given, at least one <mix> section must occur, too.
The elements describing the breathing gas are the following: <aliasname>, <ar>, <equivalentairdepth>, <h2>, <he>, <maximumoperationdepth>, <maximumpo2>, <n2>, <name>, <notes>, <o2>, <priceperlitre>
<gasdefinitions>, <tankdata>

<priceperlitre currency="EUR">0.50</priceperlitre>
