Combination of specifications

Parts of the document may be defined to belong to another specification, eg:

   <element name="htmlExample">
    <complexType>
     <sequence>
      <any namespace="http://www.w3.org/1999/xhtml"
           minOccurs="1" maxOccurs="unbounded"
           processContents="skip"/>
     </sequence>
		 <anyAttribute namespace="http://www.w3.org/1999/xhtml"/>  
    </complexType>
   </element>

means that the <htmlExample> element may contain any valid XHTML!

• namespace can be set to, eg, ##any (any well formed XML could be used)
• processContents can set to, eg, strict (schema validation in the content, too)
