Never mind -- I found where to look: in the request.xsl
logicsheet in the cocoon.jar file.
And btw, it works! (I needed to use as="object" for the array case).
Is there any documentation project going on? I'd like to
consider helping out some. Things really aren't too hard to
understand looking at the XSL but for the newcomer, it takes a
while to find out where to start.
