Inputs

(For outputs, see below)

inputsOutputs

A list of criteria with specified preference direction. List has to contains at least one criterion that will be minimized (input) and at least one criterion that will be maximized (output).

The input value should be a valid XMCDA document whose main tag is <criteria>. It must have the following form:

<criteria>
                     <criterion>
                                                     <scale>
                                                             <quantitative>
                                                                     <preferenceDirection>
