Example 1
The following example shows a declaration for an element called "person".
By using the <any> element the author can extend (after <lastname>) the content

<xs:element name="person">
<xs:complexType>
<xs:sequence>
<xs:element name="firstname" type="xs:string"/>
<xs:element name="lastname" type="xs:string"/>
<xs:any minOccurs="0"/>
