Re: paradox ?

An attempt at clarifying state/domain:

State is a property only of pgms.  It's essentially a "capability," i.e. it
indicates how powerful a pgm is.  A system-state pgm can do just about
anything--in particular, it can access system-domain objects (as well as
user-domain objects).  A user-state pgm is wimpier--it can't access
system-domain objects, only user-domain.

Domain is a property of all objects.  It's like a "protection."  System-domain
objects are "protected" from user-state pgms--only system-state pgms can access
them.  User-domain objects aren't "protected"--they can be accessed by either
user- or system-state pgms.

Therefore, API pgms are user-domain (so normal user-state pgms can call them),
and they are system-state (so they can do powerful things user-state pgms
can't, like accessing system-domain objects).
