XSL engine should use Xalan 2.7.2 bundled with portal to use extended Xalan features.

Steps to reproduce:

1. Create WCM template, XSL language with following content:

   <?xml version="1.0"?>
   <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   	<xsl:template match="/">
   		<xsl:value-of select="system-property('java.version')"/>
   	</xsl:template>
   </xsl:stylesheet>
   

1. Create WCM article with this template
2. Display WCM article

Expected result: Portlet displays error:

SecurityException when trying to access XSL system property: java.version Line #5; Column #59; 

1<?xml version="1.0"?> 
2 
3<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> 
4	<xsl:template match="/">
5		<xsl:value-of select="system-property('java.version')"/> 
6	</xsl:template> 
7</xsl:stylesheet> 

Actual result: Portlet is unavailable, NullPointerException in logs
