Complex Types

Building element structures While data types are exciting, documents need more sophisticated structures. Complex types let you assemble elements and attributes along with their types into document structures.
More than just patterns and facets Patterns and facets are great for defining atomic content, but complex types let you build molecules.

<xsd:complexType name="book">
  <xsd:element name="title" type="xsd:string"/>
  <xsd:element name="authors" type="Authors"/>
  <xsd:element name="price" type="xsd:decimal"/>
</xsd:complexType>
<xsd:complexType name="Authors">
  <xsd:elementName="author" minOccurs="1" maxOccurs="*">
    <xsd:complexType>
      <xsd:element name="givenName" type="xsd:string"/>
      <xsd:element name="familyName" type="xsd:string"/>
	<xsd:attribute name="xlink:href" type="xsd:uri-reference"/>
    </xsd:complexType>
  <xsd:elementName>
</xsd:complexType>
