// .NAME vtkSMDoubleRangeDomain - double interval specified by min and max
// .SECTION Description
// vtkSMDoubleRangeDomain represents an interval in real space (using
// double precision) specified using a min and a max value.
// Valid XML attributes are:
// @verbatim
// * min 
// * max
// @endverbatim
// Both min and max attributes can have one or more space space
// separated (double) arguments.
// Optionally, a Required Property may be specified (which typically is a
// information property) which can be used to obtain the range for the values as
// follows:
// @verbatim
// <DoubleRangeDomain ...>
//    <RequiredProperties>
//      <Property name="<InfoPropName>" function="RangeInfo" />
//    </RequiredProperties>
// </DoubleRangeDomain>
// @endverbatim
