/**
* Policy Component for managing Policies and Behaviours.
*
* This component provides the ability to:
*
* a) Register policies
* b) Bind behaviours to policies
* c) Invoke policy behaviours
*
* A behaviour may be bound to a Policy before the Policy is registered. In
* this case, the behaviour is not validated (i.e. checked to determine if it
* supports the policy interface) until the Policy is registered. Otherwise,
* the behaviour is validated at bind-time.
