Modularization with XML Schemas

• In file xhtml-image.xsd:

  <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
      <xs:element name="img">
          <xs:complexType>
              <xs:attribute name="longdesc" type="xs:string"/>
              <xs:attribute name="src" type="xs:anyURI"/>
              ...
          </xs:complexType>
      </xs:element>
  </xs:schema
	 

• In XHTML-XX schema:

	<include  schemaLocation="xhtml-image-1.xsd">	
		

Schema version is being developed now
