multi-interfaces

3.24: adda/multi-interfaces:
. just as oop classes have different interfaces for
clients vs subclassers,
adda needs a sublanguage for describing
multiple interfaces
and the various actors that can access them .
. dimensions for having separate faces include:
roles, security levels, priorities,
business arrangements (eg, cripple.ware vs full-service),
and partner name (where the degree of allowed reuse
depends on which partner is doing the reusing ).
