Should I define a java class for complextype property?

[kujunguo kujunguo]

My composite likes:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
    xmlns:xsd="http://www.w3.org/2001/XMLSchema";
        targetNamespace="http://assembly-tests";
        name="Assemby-component--Composite">

        <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
    xmlns="http://www.example.com/Customer";
targetNamespace="http://www.example.com/Customer";>

    <xsd:element name="customer" type="Customer"/>
    <xsd:complexType name="Customer">
        <xsd:sequence>
            <xsd:element name="firstName"  type="xsd:string"/>
            <xsd:element name="middleName" type="xsd:string"/>
            <xsd:element name="lastName"   type="xsd:string"/>
        </xsd:sequence>
    </xsd:complexType>
   </xsd:schema>

    <component name="CComponent">
            <implementation.java
class="org.apache.tuscany.sca.vtest.assembly.component.property.ServiceCImpl"/>
            <property name="customerInfo" xsi:type="Customer">
        
                    <firstName>Ku</firstName>
                    <middleName>Jun</middleName>
                    <lastName>Guo</lastName>
        
            </property> 
        
     </component>

</composite>

So I have to define a Customer class if I want to use it in my
implementation as following:
...
@Property Customer customer;
...

is it a valid scenario for complextype property?
