It is sometimes useful to include the same instance in several different
pages. This can be done with the <Include> element, whose
only argument is a path to the instance.
One can use this element together with <Class> and detached
instances. For example, you could define a standard footer:
<Class Footer> This page written by <A HREF="index.html">Jocelyn Ireson-Paine</A> </Class>then create a detached instance of it, say in the root of an application:
<Instance><Footer footer></Instance>and then include that at the bottom of every page:
<Include footer>
