	No need to apologize Robin - I'll be the first one to agree when
	someone has a better idea. :-)
	I've implemented Sylvain's suggestions and have posted it in a
	previous email. Thanks Sylvain.

	We just need to be aware though that such a solution is not bounded,
	and allows *any* Java code to be placed in sitemap test clauses. 
	The temptation is also there to place increasingly more and more java
	code into the sitemap, which would otherwise go into its own class.
	The only other point is that of syntax. Instead of writing something

		<when test="myparameter = 'string'">

	one has to write:

		<when test="request.getParameter(&quot;myparameter&quot;).equals(&quot;string&quot;)">

	The first is more readable, but it's minor thing.

	Personally, I like both solutions. Sylvains idea definitely answers
	many of my previous questions and will be of great use in our project.
	It also has definite performance advantages.
	For non-performance critical pipelines however, I would use the first
	solution though, due to it's readability and the boundaries it
	But that's what such an open community offers - freedom of choice! :-)

	Thanks for everyone's input. Hope everyone had a great weekend.
