If you're using 2.1 and doing if-then-else logic, it might be better to
modify the ResourceExistsSelector.  Eg, comparing:

<map:act type="resource-exists">
  <map:parameter name="url" value="content/xdocs/{1}{2}" />
  <map:generate src="content/xdocs/{../1}{../2}" />
  <map:serialize type="xml"/>
<!-- stuff to do if resource doesn't exist -->


<map:select type="exists">
  <map:when test="content/xdocs/{1}{2}">
    <map:generate src="content/xdocs/{1}{2}" />
    <map:serialize type="xml"/>
    <!-- stuff to do if resource doesn't exist -->

Making a FileExistsSelector and DirectoryExistsSelector from this
wouldn't be hard.
