    Description (
       "This class is a subclass of the abstract class "
       "SchedulingElement. It introduces a new property, "
       "WeightingFactor, to give some inputs a higher probability of "
       "being serviced than other inputs. It also introduces a "
       "Priority property, to serve as a tiebreaker to be used when "
       "inputs have equal weighting factors. As is the case with all "
       "subclasses of SchedulingElement, the input associated with an "
       "instance of WRRSchedulingElement is of one of two types: "
       "either a queue, or another scheduler. Because scheduling of "
       "this type is always work conserving, the inherited boolean "
       "property, WorkConserving, is restricted to TRUE in this class.")]

          "A 32-bit bit unsigned integer defining the weighting factor "
          "that offers some inputs a higher probability of being "
          "serviced than other inputs. The property's minimum value is "
          "0, its maximum value is 100000, and its Units are "
          "thousandths."),

      [Description (
          "A 16-bit bit unsigned integer which serves as a tiebreaker, "
          "in the event that two or more inputs have equal weights. A "
          "larger value represents a higher priority. While this "
          "condition may not occur in some implementations of a "
          "weighted round robin scheduler, many implementations "
          "require a priority to resolve an equal-weight condition. In "
          "the instances where this behavior is not necessary or is "
          "undesirable, the property may be left unspecified. \n"
