4.02, asp3.5, winxp, iis5.1

This is my first xslt. It works fine but I was wondering if there was a way to optimize the code. Mostly I am concern with the xsl:choose statement that defines how I am going to display my inline elements based upon whether or not the page has a child node or not. Thanks in advanced.
