Yep, agreed, although shouldn't the FileGenerator caching be done by the
normal caching system? Rather than tying in something at a lower level?
I'd rather see XMLCompiler integrated by having it as *one of a number*
of potential XML, um, 'transcoders' (thanks batik) usable within the
caching infrastructure. We've already had one offer of help with the
caching architecture -- would you be interested in teaming up on this?
