RE: XSL: Error Detection?

You can write a new stylesheet module which imports the current one, and
contains a single template rule of the form:

<xsl:template match="*">
<xsl:choose>
  <xsl:when test=".... node is in error subtree ...">
     ..do something.
  </xsl:when>
  <xsl:otherwise>
     <xsl:apply-imports/>
  </xsl:otherwise>
</xsl:choose>
</xsl:template>

The only caveat is that this assumes you are not using apply-templates
with parameters.
