:-) It took me a while to figure out what Gavin meant...

In Gavins psuedo code above

"when" represents <xsl:when test="@starts-with='true'">

"otherwise" represents the following <xsl:otherwise>

"if test = x" represents <xsl:if test="starts-with($path, @pattern)">

"if test = y" represents <xsl:if test="contains($path, @pattern)">

"z" represents everything inside the above <xsl:if> statements

The bit of XSL this refers to is copied below.
