Well, here is the example I just wrote.

Testing it found a bug (so you can't run it), but I fixed the bug,
locally. The output was:

<?xml etc. ?>
Tested OK.

Change the xsl:value-of to xsl:sequence prints the XML, instead of the
contents.

This is the transformation:

<?xml version="1.0" encoding="utf-8"?>
<xsl:transform 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
    xmlns:gexslt="http://www.gobosoft.com/eiffel/gobo/gexslt/extension";
   xmlns:axsl="file://namespace.alias"
    version="2.0">

  <xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl"/>
  
  <xsl:template name="initial">
    <xsl:call-template name="build"/>
    <xsl:call-template name="run"/>
  </xsl:template>
  
  <xsl:template name="build">
    <xsl:result-document href="file:///home/colin/gestalt/generated.xslt">
      <axsl:transform version="2.0">
	<axsl:template match="/">
	  <doc>
	    Tested OK.
	  </doc>
	</axsl:template>
      </axsl:transform>
    </xsl:result-document>
  </xsl:template>
  
  <xsl:template name="run">
    <xsl:variable name="generated" select="gexslt:transformation('file:///home/colin/gestalt/alias.xsl',doc('file:///home/colin/gestalt/system.xace'))"/>
    <xsl:value-of select="$generated"/>
  </xsl:template>

</xsl:transform>

This worked (after fixing the bug, which means you can't run it at
home), by first creating a symbolic link from

alias.xsl onto generated.xslt.

A real cheat.
