	The getProperties method is to make the contract more explicit [
in the absence of a 'Service' contract definition ], and to make things
easier for scripting languages - perhaps.

	Um, I would put a Persist* interface on the control, that is if
you wish to fully serialize the component's state. Clearly the PropertyBag
might only reflect a sub-set of the component's state - if you only want
to serialize that you might want to aggregate to the property bag. Of
course, if the pb reflects the whole state, you could aggregate a copy
of that interface's impl. to both... :-)

	HTH,

		Michael.
