Hi

http://www.w3.org/TR/2003/WD-xslt20-20030502/Overview-diff.html#disable-output-escaping

"20.2 Disabling Output Escaping

Normally, when using the XML, HTML, or XHTML output method, the 
serializer will escape special characters such as & and < when 
outputting text and attribute nodes. This ensures that the output is 
well-formed. However, it is sometimes convenient to be able to produce 
output that is almost, but not quite well-formed XML; for example, the 
output may include ill-formed sections which are intended to be 
transformed into well-formed XML by a subsequent non-XML-aware process. 
For this reason, XSLT defines a mechanism for disabling output escaping."

But generating mal-formed XML is not the only reason for having to rely 
on shaky d-o-e.

Until I can use s.th. like

<programlisting>
  <xsl:serialize format="xml_snippet">
   <xsl:copy-of select="$snippet"/>
  </xsl:serialize>
</programlisting>

(see
http://lists.w3.org/Archives/Public/public-qt-comments/2003Apr/thread.html#54 
)

I use

   <xsl:text
     disable-output-escaping="yes">&lt;![CDATA[</xsl:text>
   <xsl:copy-of select="$forrest"/>
   <xsl:text disable-output-escaping="yes">]]&gt;</xsl:text>

This satisfies a requirement of an IMHO not-too-esoteric usage scenario, 
and the results are well-formed. 
(http://www.w3.org/TR/REC-xml.html#NT-CDEnd must be escaped)

As long as d-o-e is one workaround for features that are not available 
in XSLT, I'm not sure if the wording is appropriate.

Perhaps adding xsl:serialize is all that's needed. Personally, I don't 
think I have a use case for d-o-e except that one: I could work around 
the missing xsl:serialize functionality without d-o-e, but it's one 
example where d-o-e is used without generating mal-formed XML.
I'd be happy about not having to rely on d-o-e.

[1] full (actual and working, but inclomplete) listing:

<xsl:template name="serialize">
   <xsl:param name="forrest"/>
   <xsl:choose>
     <xsl:when test="function-available('saxon:serialize')">
       <xsl:variable name="forrest_stripped">
         <xsl:apply-templates select="$forrest"
           mode="strip_ws_only_nodes"/>
       </xsl:variable>
       <xsl:copy-of
         select="saxon:serialize(
           $forrest_stripped,
           'xml_snippets'
         )"/>
     </xsl:when>
     <xsl:otherwise>
<!-- no indenting etc -->
   <xsl:text
     disable-output-escaping="yes">&lt;![CDATA[</xsl:text>
   <xsl:copy-of select="$forrest"/>
   <xsl:text disable-output-escaping="yes">]]&gt;</xsl:text>
     </xsl:otherwise>
   </xsl:choose>
</xsl:template>
