      <p>This function parses the contents of a processing instruction whose content follows the
conventional attribute="value" structure (as defined for the &lt;?xsl-stylesheet?&gt; processing
instruction). The context should be a processing instruction node; the function returns the value
of the pseudo-attribute named in the first argument if it is present, or an empty string otherwise.</p>
      <p>If the attribute value contains a sequence of characters in the form of an XML character reference,
for example "&amp;#x0A;", this is parsed and converted into the corresponding character.</p>
      <p><i>Although intended for parsing processing instructions, the function will actually parse the string value
of the context item whatever it might be.</i></p>
