//! # Raw capability provider interface
//! 
//! This module contains the raw capability struct. Use this facility
//! if you are building your own internal or proprietary capability provider that is not one of
//! the provider types exposed as part of the standard guest SDK. You might want to provide your own 
//! SDK that depends on this and provide a wrapper around the raw capability provider interface.
