Removing range filter operators

The PopRangeFilterOperator removes a range filter component from the state.

The syntax of this operator is:
<Operator xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:type="PopRangeFilterOperator">
  <RangeFilter AttributeName="ListPrice" />
</Operator>

The AttributeName attribute is the name of the numeric or geocode attribute for which a range filter component had been used.

If the call is successful, the following Results component is returned:
<cs:Results xmlns:cs="http://www.endeca.com/MDEX/conversation/1/0" 
    xmlns:mdex="http://www.endeca.com/MDEX/XQuery/2009/09">
   <cs:Request>
      <cs:State/>
   </cs:Request>
</cs:Results>

The empty State element shows that the range filter component was successfully removed.
