Another possibility (untested) is for your App to create a lockfile while it is writing out the XML document and then remove the lockfile when the document write is completed. Within your XSL have a test to see if the lockfile exists and do nothing if it exists.

 Help with Code Tags 
 XML, XSLT and XPATH Syntax (Toggle Plain Text) 
   <xsl:variable name="lockexists">
      <xsl:choose>
         <xsl:when test="document('/tmp/lockfile')">true</xsl:when>
         <xsl:otherwise>false</xsl:otherwise>
      </xsl:choose>
   </xsl:variable>
   <xsl:variable name="lockexists">
      <xsl:choose>
         <xsl:when test="document('/tmp/lockfile')">true</xsl:when>
         <xsl:otherwise>false</xsl:otherwise>
      </xsl:choose>
   </xsl:variable>

The lockfile should be a simple XML document with a different namespace so that document() does not complain.
