How to map xsd restrictions and constraints to customized user messages


I’m testing this wsdl attributes to control some fields :

<xsd:simpleType name="montantPrelevement">
     <xsd:restriction base="xsd:double">
     <xsd:minExclusive value="0.0"/>

and if I test the associated web service with a wrong value (-5), I obtain this normal message :

            <webM:exception xmlns:webM="">
               <webM:message xml:lang="">[ISC.0049.9005] Input validation for service '' failed: '/prelevementImmediat/montantPrelevement DT-009 [ISC.0082.9492] Value is less than or equal to minExclusive'</webM:message>

Is this any way to map this error with a customized error (like below), to avoid these technical informations shared to third party ?

   <msg>The prelevementImmediat/montantPrelevement value is incorrect (positive numeric value required)</msg>

Maybe the Content Type can be me mapped to user messages somewhere in WebMethods ?
