Description:
------------
When attempting to do an XSL transformation using the 
new DOM and XSL extensions available in PHP 5, I've 
noticed entities aren't expanded in the output. If I 
import the DOM object into SimpleXML, the entities are 
expanded.

The first time I attempted to run the following code I 
was using PHP 5 RC3, libxml2 2.6.10, and libxslt 1.1.7. 
I am now using CVS versions of PHP 5, libxml2, and 
libxslt in order to see if this was a bug fixed in 
either PHP 5, libxml2, or libxslt. The CVS versions I'm 
using were downloaded June 18th.

I run Apache 1.3.31 under Mac OS 10.2.8. I don't recall 
seeing any errors when I built and installed Apache, 
PHP, libxml2, or libxslt.

Reproduce code:
---------------
<?php
$xml = <<<EOD
<!DOCTYPE example [
<!ENTITY entity1 "Entity 1">
<!ENTITY entity2 "Entity 2">
]>
<example>
  <element1>Example Document</element1>
  <element2>&entity1;</element2>
  <element3>&entity2;</element3>
</example>
EOD;

$xsl = <<<EOD
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="example">
    <p>XSL Element 1: <xsl:value-of select="element1" /></p>
    <p>XSL Element 2: <xsl:value-of select="element2" /></p>
    <p>XSL Element 3: <xsl:value-of select="element3" /></p>
  </xsl:template>
</xsl:stylesheet>
EOD;

$xmlDocument = new DomDocument;
$xmlDocument->loadXML($xml);
$xslDocument = new DomDocument;
$xslDocument->loadXML($xsl);
$processor = new XsltProcessor;
$processor->importStyleSheet($xslDocument);
print $processor->transformToXML($xmlDocument);

$xmlDocument = simplexml_import_dom($xmlDocument);
print '<p>SimpleXML Element 1: ' . $xmlDocument->element1 . '</p>';
print '<p>SimpleXML Element 2: ' . $xmlDocument->element2 . '</p>';
print '<p>SimpleXML Element 3: ' . $xmlDocument->element3 . '</p>';
?>

Expected result:
----------------
XSL Element 1: Example Document

XSL Element 2: Entity 1

XSL Element 3: Entity 2

SimpleXML Element 1: Example Document

SimpleXML Element 2: Entity 1

SimpleXML Element 3: Entity 2

Actual result:
--------------
XSL Element 1: Example Document

XSL Element 2: 

XSL Element 3: 

SimpleXML Element 1: Example Document

SimpleXML Element 2: Entity 1

SimpleXML Element 3: Entity 2
