Thanks for this. The user makes a choice from a drop down menu on the
rendered page and then an xsl:when reads some of the XML to see which
one is loaded and applies it.

I got it to work late yesterday with an xsl:if reading the same values
to work out which style sheet had been loaded to select the correct
buttons to present.
