*nod*. I understand your rationale.
I had intended to use the parent CM concept to create a second CM that
would manage my application's components, separately from cocoon's CM.
I had thought that using cocoon's CM to manage my application's
components was the wrong thing to do, because it required modifying the
cocoon.xconf and cocoon.roles files - part of cocoon and not our
application. Was this assumption false ?

Ok. Thanks for the tip mate - How does this patch look ? :-)
Cheers,
