      public class DoubleRangeFieldValidator
      extends FieldValidatorSupport

  Field Validator that checks if the double specified is within a certain range.
  - fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
  - minInclusive - the minimum inclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
  - maxInclusive - the maximum inclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
  - minExclusive - the minimum exclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
  - maxExclusive - the maximum exclusive value in FloatValue format specified by Java language (if none is specified, it will not be checked)
  - minInclusiveExpression - the minimum inclusive value specified as a OGNL expression (if none is specified, it will not be checked)
  - maxInclusiveExpression - the maximum inclusive value specified as a OGNL expression (if none is specified, it will not be checked)
  - minExclusiveExpression - the minimum exclusive value specified as a OGNL expression (if none is specified, it will not be checked)
  - maxExclusiveExpression - the maximum exclusive value specified as a OGNL expression (if none is specified, it will not be checked)
  You can specify either minInclusive, maxInclusive, minExclusive and maxExclusive or minInclusiveExpression, maxInclusiveExpression, minExclusiveExpression and maxExclusiveExpression as a OGNL expression, see example below. You can always try to mix params but be aware that such behaviour was not tested. Do not use ${minInclusiveExpression}, ${maxInclusiveExpression}, ${minExclusiveExpressionExpression} and ${maxExclusive} as an expression as this will turn into infinitive loop!
