I had a bug report the other day that was full of things like

<xsl:template match="&xyz-pattern;">
  <xsl:for-each select="&abc-expression;">

and when you looked at the DTD, the entities were all built up by expansion
of parameter entities N deep. I've never seen anything so hard to follow in
all my life.
