XSD: ComplexType

Question

I have a complexType like:

<xsd:complexType name="NightlyRate">
    <xsd:complexContent>
        <xsd:extension base="com:Money">
            <xsd:attribute name="night" type="com:Number" use="required"/>
        </xsd:extension>
    </xsd:complexContent>
</xsd:complexType>

Now, I want to add a child element to "NightlyRate", which itself is of complexType. I tried adding:

<xsd:element name="xxx" type"com:Money"/>

after the complexContent element, but it throws error that element is not expected, also part of the problem is type of this complex-element is the same as type of extension base. I am using JAXB. Is there any other way to achieve this?

Thanks!

Answer 1

To get sub-elements in a xsd:complexType , you have to put a xsd:sequence in it (first level, along with annotations and attributes), wich states that you want well... sub-elements. In this sequence, you can include elements of other defined types or define new types.

See XSD complex elements at W3Schools , and womp's example.

In some cases, you may want to use the xsd:any element to allow yet-undefined extensions (loose).

<xsd:complexType name="NightlyRate">
    <xsd:complexContent>
        <xsd:extension base="com:Money">
            <xsd:sequence>
                <xsd:element name="xxx" type"com:Money">
                   <xsd:complexType>
                      <xsd:complexContent>
                             /// Attributes here
                      </xsd:complexContent>
                   </xsd:complexType>
                </xsd:element>
            </xsd:sequence>

            <xsd:attribute name="night" type="com:Number" use="required"/>
        </xsd:extension>
    </xsd:complexContent>
</xsd:complexType>
