      <h1>saxon:generate-id()</h1>
      <p><b>saxon:generate-id($node as node()) =&gt; xs:string</b></p>
      <p>This function returns a string that acts as a unique identifier for the supplied node. The identifier will
 always consist of ASCII letters and digits and will start with a letter.</p>
      <p>The function is identical to the XSLT generate-id() function. It is provided as an extension function in the
         Saxon namespace to make it available in contexts other than XSLT, for example in XQuery.</p>
      <p><i>This function is obsolescent, since the <code>generate-id()</code> function is
               available in XPath 3.0 and XQuery 3.0.</i></p>
