Subject: Re: [wsrp-wsia] [I#175] Roles should be per-Entity and not per-Producer

I'm concerned that if we keep roles we are establishing a precedent for
specs defining things that belong elsewhere (security in this case). It is
not realistic to think that WSRP is all that will be involved in the
communications between the two parties or that it should define what all of
the other things are. We should be focussed on the protocol relative to
content generators being accessible as web services. Anything outside that
domain is treading on thin ice.

I'm concerned that if we dropped roles altogether, no matter how
dicey or messy it is to keep them, we would see dozens of different
extensions added into the mix by producers and consumers, but if we
can make a clear but very simple way to include them, we stand a
better chance of having fewer wildly different kinds of role
verification put in use willy nilly. I agree it should be per entity
(or portlet if we settle on that as the name of the great thingie).
