Use the indentity template (see the other post a few minutes ago) with:

<xsl:template match="device">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
    <xsl:copy-of select="document('file:/c:/path/to/file2.xml')/device/param"/>
  </xsl:copy>
</xsl:template>

This assumes you are processing file1.xml and want to include
file2.xml - you'd probably want to separate out the path to a
parameter.
