Clients making HTTP requests on behalf of agents (social entities) may need to be given different set of access privileges than the agents.

Considerations:

• Client is authenticated - protocol agnostic.
• Specific predicate for the client (eg. acl:client as possibly a subPropertyOf acl:agent) vs. reuse acl:agent since the object ie. the WebID that's changing.
• Access privileges given to a client is same as agent's or can be different.
• Related but may not be relevant: whether an access subject (eg. agent, agentGroup, agentClass) delegates (acl:delegates) a client to act on behalf of the agent.
