I have done some experiments with this. Here is what I have so far (briefly
tested with XEP 4.4): 

<!-- Set to 1 to generate changebars -->
<xsl:param name="use.xep.changebars">1</xsl:param> 

<xsl:template match="*[@revisionflag='changed']">
  <xsl:choose>
    <xsl:when test="$use.xep.changebars != 0 and $xep.extensions != 0">
      <xsl:variable name="class" select="generate-id(.)"/>
         
	<rx:change-bar-begin change-bar-class="{$class}"
change-bar-placement="outside" change-bar-style="solid"
change-bar-color="red" xmlns:rx="http://www.renderx.com/XSL/Extensions"/>

	<xsl:apply-imports/>
	
	<rx:change-bar-end change-bar-class="{$class}"
xmlns:rx="http://www.renderx.com/XSL/Extensions"/>
      
    </xsl:when>
    <xsl:otherwise>
     	 <xsl:apply-imports/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
