The LogTarget is in LogKit and the LogTargetFactory is in Excalibur.

Maybe a hack, but a nice hack ! I was really impressed by this idea 
which helps a lot to serve documents that have to be decomposed in 
several subdocuments because of the limitations of http.

Instead of removing is abruptly, it would be better to add a flashy 
warning about clustering issues in the javadocs and plan a rewrite in 
the todo list.

I also thought of using your nice XMLCompiler to store fragments instead 
of building a DOM to speed up things.

if someone else wants to do it !
