    <title>Country selector</title>
    <para>This example illustrates how you can programmatically update the
      content of a selection list using a collection built in the flow.</para>
    <para>
      This sample illustrates event-handling in Woody and how selection lists can be changed
      programmatically.
    </para>
    <para>
      Event-handlers are defined in the form definition to update the selection lists and
set
      the comment text below the table. This requires only a few lines of server-side JavaScript.
      Selection widgets also have a "submit-on-change" attribute set in the form template
so that
      changes are considered immediately by the server.
    </para>
    <para>
      See "countryselector_form.xml" and "countryselector_template.xml" to see how this is
done.
