id=unique identifier of this parameter set for the Varying Permeability Model — compulsory

The element <vpm> describes the parameter set for a Varying Permeability Model (VPM) (see D.E. Yount, D.C. Hoffman, On the Use of a Bubble Formation Model to Calculate Diving Tables, Aviation, Space and Environmental Medicine, February 1986). Several <vpm> sections may appear inside <decomodel> so that different parameter sets can be used with the model.
