It's not clear to me either! :/
The Javadoc at the top of 
http://svn.wyona.com/repos/public/yanel/trunk/src/impl/java/org/wyona/yanel/impl/resources/usecase/ExecutableUsecaseResource.java 
might help.

Also maybe moving the unrelated Jelly functionality from UsecaseResource 
into a separate class for reuse outside of usecases might help clear 
things up.
Although I am not sure we should do allow encourage access to Jelly 
right now or even at all, given the current Jelly encoding problems ( 
see http://bugzilla.wyona.com/cgi-bin/bugzilla/show_bug.cgi?id=5964 ) 
and that I lately realized that debugging in Jelly seems to be only 
poorly supported: for example incorrect Jelly expressions are simply 
ignored, which is even worse than XSLT... :(
