My concern in my inital post was that the lazy evaluation (delayed
evaluation of the variable) might result in the file being opened by
xt:document for writing before it gets opened by document() for reading.
I just experimented a little and discovered that this is not so much of
a concern, though you do need to call document() outside the xt:document
block.  So, instead of saving stuff into a variable, you can just do
something like the following, and subset the document using a select on
xsl:copy-of or xsl:apply-templates as suggested by Mike Kay and David
Carlisle.

 Steve

<xsl:template match="file">
  <xsl:variable name="path" select="."/>
  <xsl:variable name="contents" select="document($path)"/>
  <xt:document method="html" href="{$path}">
    <xsl:apply-templates select="$contents"/>
  </xt:document>
</xsl:template>
