Boolean attribute filters

Filtering by Boolean attribute assignments is supported.

You can specify the Boolean value as true or false (in either upper- or lower-case).

For example, this query filters on assignments of false in the Boolean attribute named AFFINITY_CARD:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header/>
   <soapenv:Body>
      <Request xmlns="http://www.endeca.com/MDEX/conversation/2/0">
        <Language>fr</Language>
        <State>
          <DataSourceFilterString>COUNTRY_NAME = 'France'</DataSourceFilterString>
          <SelectionFilterString>AFFINITY_CARD = false</SelectionFilterString>
        </State>
        <ContentElementConfig xsi:type="RecordListConfig"
          HandlerFunction="RecordListHandler"
          HandlerNamespace="http://www.endeca.com/MDEX/conversation/handlers/2010"
          Id="RecordList" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        </ContentElementConfig>
       </Request>
    </soapenv:Body>
</soapenv:Envelope>
Each returned record should have the following assignment:
<cs:Record>
   ...
   <AFFINITY_CARD type="mdex:boolean">false</AFFINITY_CARD>
   ...
</cs:Record>
