Inside the <decomodel> section information concerning the decompression model(s) used is given. At time the three most spreaded decompression models Bühlmann, Reduced Gradient Bubble Model (RGBM), and Varying Permeability Model (VPM) are supported. The Bühlmann model as well as the VPM are published and the parameters used are wellknown. Contrarily, Bruce Wienke's Reduced Gradient Bubble Model is a "proprietary" model and its parameters are not completely known yet. Therefore support for the latter model is only insufficient.
