Right. That's the source document.

(In fact I have quite a few docs that were broken into pieces using
entities that are screaming for XInclude instead. The problem with
entities is you can't validate individual pieces separately since the
XML header and doctype declaration are only present in the master file)

Well, I'm using xerces-j2 2.6.2 which is supposed to be fairly recent.

Or are you telling me the xerces people have no XInclude support nor are
planning for one ? Short-term I can work around this using the following
stylesheet (since I only need the most basic of XInclude support now)
but that means yet another bunch of intermediary files I have to track.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:xi="http://www.w3.org/2003/XInclude"
                version="1.0">
  <xsl:output method="xml" indent="yes" encoding="UTF-8"/>
  <xsl:template match="*">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <xsl:apply-templates select="*"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="@*">
    <xsl:copy/>
  </xsl:template>
  <xsl:template match="xi:include">
    <xsl:apply-templates select="document(@href)/*"/>
  </xsl:template>
</xsl:stylesheet>
