      <h1>xsl:processing-instruction</h1>
      <p>The <code>xsl:processing-instruction</code> element can appear anywhere within an 
<code>xsl:template</code>.
 It causes an XML processing
instruction to be output.</p>
      <p>There is a mandatory <code>name</code> attribute which gives the name of the PI. This attribute is interpreted
as an <i>attribute value template</i>, so it may contain string expressions within curly braces.</p>
      <p>The data part of the PI may be given either by a <code>select</code> attribute or by an enclosed
sequence constructor. If the <code>select</code> attribute is used and the value is a sequence, then
the items in the sequence are output space-separated.</p>
      <p>For example:</p>
      <div class="codeblock"
           style="border: solid thin; background-color: #B1CCC7; padding: 2px">
         <pre>
            <code>&lt;xsl:processing-instruction name="submit-invoice"&gt;version="1.0"&lt;/xsl:processing-instruction&gt;</code>
         </pre>
      </div>
      <p>Note that special characters occurring within the PI text will <i>not</i>
be escaped.</p>
