Have you tried src="cocoon:raw:/a" here? "cocoon:raw" creates a new 
"naked request" where the parameters of the original request are 
ommitted, and maybe resets the view also (although I'm not sure after a 
quick look at EnvironmentWrapper).

Otherwise, the view is called twice, and the result is the 
pretty-printing of the pretty-printed version of "test.xml".
