It has been a while since I did anything with XSLT, but if I recall you
might get some use out of xsl:invoke (for all I know the name of the tag
may of changed) where you can in a sense "goto" a stylesheet defined
macro.  So you could have:

<xsl:choose>
  <!-- Error -->
  <xsl:when test="foo">
    <xsl:invoke macro="End">
    <xsl:invoke>
  </xsl:when>
</xsl:choose>

<xsl:macro name="End">
  Exit
<xsl:macro>

Forgive me if I am wrong on the actual syntax as I have not had much to do
with XSL for about 6 months now.  Just trying to help.
