      <p class="subhead">Notes on the Saxon implementation</p>
      <p>Saxon implements the zero-argument function by passing a null URI to the registered 
    <code>CollectionURIResolver</code>. The default <code>CollectionURIResolver</code>
    implementation supplied with the product handles this by returning an empty sequence, 
    but a user-supplied <code>CollectionURIResolver</code> is free to handle this case any way it wishes.</p>
      <p>If a user-defined <code>CollectionURIResolver</code> has been registered, the action
    of this function is entirely user-defined. A resolver may be registered using
the <code>setCollectionResolver()</code> method on the <code>Configuration</code> object, or (in XSLT)
using <code>setAttribute()</code> on the <code>TransformerFactory</code>. The <code>CollectionURIResolver</code>
may also be nominated using the -cr option on the command line. </p>
      <p>For details of the behavior of the standard <code>CollectionURIResolver</code>,
see <a class="bodylink" href="../../sourcedocs/collections.xml">Collections</a>.</p>
