Namespaces, XLink, XML Base

• We would like to improve the example a bit:

    <Note>We would like to add a <a href="http://...">link!</a></Note>

• We could define it ourselves and... reinvent the wheel!
• The XLink and XML Base recommendations exist already
  • Let us "borrow" the recommendations instead:

    <Addresses xmlns:xlink="http://www.w3.org/1999/xlink" ... >

     ....

     <Note>Use a <a xlink:href="http://...">link!</a></Note>

    </Addresses>

• Semantics is clearly defined for our application
• A toolkit implementing xlink might be around already
• We now have our full address list...
