Re: [ebsoa] all service providers are proxies???

Duane,

I prefer to view this as a context driven model.

That is much different from the old coders view of
parameters - since the parameter may infact be
a rule, or set of rules, or a pointer to rules, or
pointer to a context instance - as
we are currently implementing in BPSS....

This view of context driven models may well
outlive the simple parameteristic view...
