Bug description: xslt_error handling

Hi,

again - the error handling issue.
I read the closed bugs and am surprised at the speed at which they are closed.

First of all - a documentation issue:
xslt_set_error_handler isn't documented. Thank you for mentioning it briefly, and then letting me figure out the arguments the called function needs.

Secondly - dying with a Fatal error, DOES occur, when the error handler isn't set! Even when using  <email protected>

Try this one:
<?php

$xslData = '<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="article">
    <table border="1" cellpadding="2" cellspacing="1">
        <tr>
            <td width="20%">
             &#160;
            </td>
            <td width="80%">
                <h2><xsl:value-of select="title"/></h2>
                <h3><xsl:value-of select="author"/></h3>
                <br/>
                
                <xsl:copy-of select="p"/>
            </td>
        </tr>
    </table>
</xsl:template>

</xsl:stylesheet>';

$xmlData = '<?xml version="1.0"?>
<article>
    <title>Learning German</title>
    <author>Sterling Hughes</author>
    <p>
        Essential phrases:
        <br>
        K&#246;nnen Sie mir sagen, wo die Toilette ist?<br/>
        Ein grosses Bier, bitte!<br/>
        Noch eins, bitte.<br/>
    </p>
</article>';
function xsl_error($errno, $errstr)
{
        echo "\$errorstr: $errstr<BR>";
        return false;
}
//xslt_set_error_handler("xsl_error");
if ( <email protected>($xslData, $xmlData, $result)) {
    echo "Here is the brilliant in-depth article on learning";
    echo " German: ";
    echo "<br>\n<br>";
    echo $result;
} else {
    echo "There was an error that occurred in the XSL transformation...\n";
    echo "\tError number: " . xslt_errno() . "\n";
    echo "\tError string: " . xslt_error() . "\n";
    //exit;
}
?>
</BODY>
</HTML>

You won't see the closing body and html tags.

Uncommenting the xslt_set_error_handler() will. The errorstr output, however - is numeric.
So can we at least have updated documentation on how to trap errors? And how xslt_set_error_handler() must be used?
