#Brent Hendricks <brentmh@ece.rice.edu> spots an import precedence problem
##I've been looking at the 4suite package (4xslt in particular). Let me
##first say that so far I am impressed with its speed and adherance to
##the XSLT spec.
##I did find a bug, however, regarding import precedence. Suppose you
##have an "outer" stylesheets that imports two "inner" stylesheets as in
##the following:
##<xsl:import href="inner1.xsl"/>
##<xsl:import href="inner2.xsl"/>
##According to the XSLT spec, elements in inner2 should have a higher
##import precedence than elements in inner1. It appears to me that
##4xslt is giving elements in inner2 a *lower* precedence.
##I'm attaching an example that demonstrates this behavior. Both
##inner1.xsl and inner2.xsl match the document tag in test.xml. inner1
##outputs the word "Failure" and inner2 outputs the word "Success".
##outer.xsl imports inner1 and then inner2.
##When you apply outer.xsl to test.xml with 4xslt, you will get the word
##"Failure" indicating that the template in inner1 was applied. The
##expected behavior is to see the word "Success" indicating that the
##template inner2 was applied.
