I tried this:


       final Writer out = new StringWriter();
       final Source in = new StreamSource(
               new StringReader( "<test><div>&mdash;</div></test>") );

       transformer.transform( in, new StreamResult( out ) );
       System.out.println( out );

And got an error:

[Fatal Error] :1:19: The entity "mdash" was referenced, but not declared.
ERROR:  'The entity "mdash" was referenced, but not declared.'

So it's been a rather long while since I played with XSLT, but it seems 
to me that it might be your document builder that is protecting you, and 
the XSLT is just spitting out what it gets in.  I forget though how to 
get XSLT to recognize the HTML entities though.  Search Google might 
offer some clues.
