Detailed Description

The wire description of an action invocation.

Names the action (name) and the specific instance (id), lists the a11::data::Port bindings for its inputs and outputs, and carries per-call headers. This is what a peer sends to dispatch an action and what an a11::actions::Action produces to describe itself.
