[xsde-users] Would you please have a look at this exception

Hello,
    I met a problem when I using XSDe parsing following xml document:
    <subnet id="98345D87DC77AECB98DF362977"> 
     <sector id=""/> 
     <sector id="A34131"/> 
    </subnet>  
    The schema is defined as:
    <xs:complexType name="subnetType">
     <xs:sequence>
      <xs:element name="sector" type="mi:sectorType" minOccurs="0" maxOccurs="64"/>
     </xs:sequence>
     <xs:attribute name="id" type="mi:hexBin104Type" use="required"/>
    </xs:complexType>
 
    <xs:complexType name="sectorType">
      <xs:attribute name="id" type="mi:hexBin24Type" use="required"/>
    </xs:complexType>
 
    <xs:simpleType name="hexBin104Type">
     <xs:restriction base="xs:hexBinary">
      <xs:length value="13" fixed="true"/>
     </xs:restriction>
    </xs:simpleType>
 
    <xs:simpleType name="hexBin24Type">
     <xs:restriction base="xs:hexBinary">
      <xs:length value="3" fixed="true"/>
    </xs:restriction>
   </xs:simpleType>
 
    The issue is that, when sector id is NULL, std::exception was threw out instead of xml::exception I supposed. I can't get any useful infomation from this exception. Seems the XSDe will not check the length of hexBinary I defined in the schema which could be checked in my own code when setting values, my question is how can I check if the hexBinary is NULL before std::exception was threw out?
    Thanks so much!
