Trouble using SOAP::Lite to create array of booleans

I am trying to create the following complexType (weatherParametersType)
and my code (see below)  isn't capturing the array of booleans correctly

(see SOAP message below).  SOAP::Lite is treating the booleans as
integers. Can anyone suggest a way to create the
weatherParametersType in Perl/SOAP::Lite?:

<xsd:complexType name="weatherParametersType">
  <xsd:all>
   <xsd:element name="maxt" type="xsd:boolean"/>
   <xsd:element name="mint" type="xsd:boolean"/>
   <xsd:element name="temp" type="xsd:boolean"/>
   <xsd:element name="dew" type="xsd:boolean"/>
   <xsd:element name="pop12" type="xsd:boolean"/>
   <xsd:element name="qpf" type="xsd:boolean"/>
   <xsd:element name="sky" type="xsd:boolean"/>
   <xsd:element name="snow" type="xsd:boolean"/>
   <xsd:element name="wspd" type="xsd:boolean"/>
   <xsd:element name="wdir" type="xsd:boolean"/>
   <xsd:element name="wx" type="xsd:boolean"/>
   <xsd:element name="waveh" type="xsd:boolean"/>
   <xsd:element name="icons" type="xsd:boolean"/>
  </xsd:all>
 </xsd:complexType>

</xsd:schema>
</types>

<message name="NDFDgenRequest">
   <part name="latitude" type="xsd:decimal" />
   <part name="longitude" type="xsd:decimal" />
   <part name="product" type="typens:productType" />
   <part name="startTime" type="xsd:dateTime" />
   <part name="endTime" type="xsd:dateTime" />
   <part name="weatherParameters" type="typens:weatherParametersType" />

</message>

using the following Perl

$latitude = 38.99;
$longitude = -77.99;
$product = "time-series";
$startTime = "2004-01-01T00:00:00";
$endTime = "2009-12-25T00:00:00";
$weatherParameters{"maxt"} = '1';
$weatherParameters{"mint"} = '0';
$weatherParameters{"temp"} = '0';
$weatherParameters{"dew"} = '0';
$weatherParameters{"pop12"} = '0';
$weatherParameters{"qpf"} = '0';
$weatherParameters{"sky"} = '0';
$weatherParameters{"snow"} = '0';
$weatherParameters{"wspd"} = '0';
$weatherParameters{"wdir"} = '0';
$weatherParameters{"wx"} = '0';
$weatherParameters{"waveh"} = '0';
$weatherParameters{"icons"} = '0';

$NDFD_XML =  SOAP::Lite

->service('http://weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl')
                 ->NDFDgen($latitude, $longitude, $product, $startTime,
$endTime, %weatherParameters);

Here is the SOAP message and it is not using booleans in the
<weatherParameters> element nor does it seem to be creating an array.
