The xinclude-from-sequence[1] component offers one solution for a
special case of a general problem. In the absence of that component,
is the following pipeline legal? If not, what constraint in the
specification[2] does it violate? If it is, what does it produce? Are
all implementations required to produce the same result? If not, why
not?

<p:pipeline xmlns:p="http://www.w3.org/2007/03/xproc"
	    xmlns:xi="http://www.w3.org/2001/XInclude">
<p:output port="result"/>

<p:xslt2>
  <p:input port="source">
    <p:inline>
      <doc/>
    </p:inline>
  </p:input>
  <p:input port="stylesheet">
    <p:inline>
      <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
		      xmlns:xs="http://www.w3.org/2001/XMLSchema"
		      exclude-result-prefixes="xs"
		      version="2.0">

	<xsl:output method="xml"/>

	<xsl:template match="/">
	  <xsl:result-document href="http://some-imaginary-dns-name.tld/document">
	    <chapter>
	      <title>Chapter Title</title>
	      <para>Some paragraph.</para>
	    </chapter>
	  </xsl:result-document>
	</xsl:template>
      </xsl:stylesheet>
    </p:inline>
  </p:input>
</p:xslt2>

<p:xinclude>
  <p:input port="source">
    <p:inline>
      <document>
	<title>Document Title</title>
	<xi:include href="http://some-imaginary-dns-name.tld/document"/>
      </document>
    </p:inline>
  </p:input>
</p:xinclude>

</p:pipeline>


                                        Be seeing you,
                                          norm
