Whether it is possible at all depends on the XSLT processor you use, for 
instance for Saxon there is an extension element described here:
<http://www.saxonica.com/documentation/extensions/instructions/entity-ref.html>
You would use that as follows
<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="2.0"
   xmlns:sx="http://saxon.sf.net/"
   extension-element-prefixes="sx">

   <xsl:output
     method="xml"
     doctype-system="test2007090601.dtd"/>

   <xsl:template match="/">
     <test><sx:entity-ref name="foo"/></test>
   </xsl:template>


</xsl:stylesheet>

where obviously you would need to make sure that test2007090601.dtd 
defines an entity named foo.

I don't think that Microsoft's XSLT processors like MSXML or 
XslCompiledTransform offer such a feature.
