Description:
------------
When attempting to do an XSL transformation using the new DOM and XSL extensions available in PHP 5 RC 3, I've noticed entities are not expanded in the output. If I import the DOM object into SimpleXML, the entities are expanded.

I run Apache/2.0.48 (Unix). I don't recall 
seeing any errors when I built and installed Apache, 
PHP, libxml2, or libxslt.

libxslt 1.1.8
libxml 	2.6.11

./configure --prefix=/usr --sysconfdir=/etc/ --with-apxs2 --with-config-file-path=/etc --with-zlib --with-bz2 --enable-ftp --with-gettext --with-iconv --with-mysql=/usr --with-ncurses --enable-mbstring=ru --enable-mbregex --enable-mbstr-enc-trans --with-png --with-pgsql --disable-short-tags --with-xsl --with-libxml --with-gd --without-sqlite

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;

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

$xmlDocument = simplexml_import_dom($xmlDOM);
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
