Re: Multiple output types and embedded documentation

Obviously I needed more exclamation marks in my subject !!!! It took
so long for anyone to respond, I thought it must have been deleted
somewhere and I'd have to repost.

Precisely.

David Carlisle has already posted one answer to these questions, but
I think it should be possible to have a more general solution, where
the user can use whatever namespaces they like, and command line
parameters are given to the "intermediate step" stylesheet, to extract
the correct outputs.

This intermediate stylesheet might contain code like this (not tested):

<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                >

<!--
  Default values are unlikely namespaces.
  We'd need "output_ns" to possibly be a list of namespaces,
  (I use [ns_1][ns_2] kind of strings, and split the string
  up in the XSL), so that you could output HTML and DEBUG.
-->
<xsl:param name="logic_ns"    select="'***'" />
<xsl:param name="output_ns"   select="'***'" />

<xsl:variable name="xsl_ns"
    select="'http://www.w3.org/1999/XSL/Transform'" />

<xsl:template match="*[namespace-uri(.) = $logic_ns]">
  <!-- probably not the right way to do the following -->
  <xsl:element name="local-name(.)" namespace="{$xsl_ns}">
    <xsl:copy-of select="@*" />
    <xsl:apply-templates />
  </xsl:element>
</xsl:template>

<xsl:template match="*[namespace-uri(.) = $output_ns]">
  <!-- strip namespace -->
  <xsl:element name="local-name(.)">
    <xsl:copy-of select="@*" />
    <xsl:apply-templates />
  </xsl:element>
</xsl:template>

</xsl:stylesheet>

A command line might look like this (where I've come up with a new
suffix) :

xslt-processor \
  template_stylesheet.txsl \        # in
  intermediate_stylesheet.xsl \     # transform
  logic_ns='org.hedley.xsl_logic' \ # the logical choice!
  output_ns='[org.hedley.html][org.hedley.xsl_trace]' \ # html + debug
  > html_debug_processor.xsl        # output
