[Pgi-wg] OGF PGI - Security Strawman

[Duane Merrill]

Since we are talking about dynamically advertising the requirements of
services (and not clients) within hypothetical information services, we
should talk explicily about "service plumbing" and not "client plumbing".
For example:

   - Service endpoint *requires *xyz (e.g., delegation-step, WS-Addressing
   reference parameters, TLS mutual authentication, etc.)
   - Service endpoint *can accept* xyz (e.g., TLS proxy-path-validation,
   SOAP WS-S proxy-path-validation, PGI VOMS-ACs, PGI SAML ACs, TLS
   client-anonymous authentication, etc)

It is implicit that we will be putting in effort to implement clients that
fit within the realm of options provided by the services that those clients
intend to use.  (And it is has become clear from several from these email
threads which services those are.)

Thus "grid islands" become "grid DAGs".
