A little HowTo

Yes, but #canBeRoot should return "true" instead of "True".

Otherwise it will return the Boolean subclass "True" instead of
its sole instance "true" and the code will not work.

Thanks

Also, #canBeRoot is *strictly* for the admin GUI. If the application already
registers itself programmatically (which yours does), no need for #canBeRoot.

True, though it's a bit confusing to go into the UI (could be either the web or OB UI eventually) and see a root component selected that is not in the list of possible UI components (and this could potentially cause problems with some UIs when saving the form -- not sure if it actually does at the moment or not).

I think it's currently good practice to tag the expected root components of your application with #canBeRoot -- if nothing else it helps document how your application is supposed to be used.
