Paul, 

Please see the docs on Class Creation/Mapping available here: 

    http://www.castor.org/sourcegen.html#Class-Creation/Mapping

In order to get what you want, your schema needs to be defined to
facilite this. By wrapping your <complexType>s in an <element> you
should get what you want. Below is the fixed up schema that should
work for you:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:bulk="urn:trivininc.com/bulk" targetNamespace="urn:trivininc.com/bulk"
elementFormDefault="qualified" attributeFormDefault="unqualified">

    <xsd:element name="VehicleTitle">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="Owner" type="bulk:Party"/>
                <xsd:element name="Registrant" type="bulk:Party"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>

    <xsd:element name="Lien">
        <xsd:complexType>
            <xsd:all>
                <xsd:element name="LienID" type="xsd:string"/>
                <xsd:element name="Lienholder" type="bulk:Party"/>
            </xsd:all>
        </xsd:complexType>
    </xsd:element>

    <xsd:element name="Party">
        <xsd:complexType>
            <xsd:all>
                <xsd:element name="LastName" type="xsd:string"/>
                <xsd:element name="FirstName" type="xsd:string"/>
            </xsd:all>
        </xsd:complexType>
    </xsd:element>

</xsd:schema>
