Select a pdf and specify its corresponding parameters. Id of the uncertain parameter/variable. Not used. Depricated. Specify whether this parameter is to be calibrated (isActive=true) or not (isActive=false). Select an auto-correlation model and specify its corresponding parameters. Id of the uncertain parameter/variable. Specify whether this parameter is to be calibrated (isActive=true) or not (isActive=false). Select how parameter variation is defined. Specify the range of possible values in term of minimum and maximum values. Specify the range of possible values in term of a percentage with respect to basic value. Id of the uncertain parameter/variable. Specify whether this parameter is to be calibrated (isActive=true) or not (isActive=false). Configuration of uncertainty characteristics of the uncertain parameters / variables. Specify the representation type of uncertainty. Possible types are ProbabilityDistributionFunction, VariationPerParameter, and AutoCorrelation. Specify the probability distribution function of the uncertain parameter/variable. Specify the variation-per-parameter of the uncertain parameter/variable. Specify the auto-correlation of the uncertain parameter/variable. version number to check if XML file is compatible with this schema
