/**
* A container class for an Apex policy model. This class is a container class that allows an Apex
* model to be constructed that contains definitions of all the context, event, and policy concepts
* required to run policies in Apex. The model contains schema definitions, definitions of events
* and context albums that use those schemas, definitions of tasks for policies and definitions of
* the policies themselves.
*
* An Apex policy model is an important artifact in Apex. At editing time, an Apex editor creates
* and edits a policy model and a policy model is loaded into and is executed by an Apex engine.
* Therefore, an Apex model and the set of policies that it holds is the way that the policy domain
* that an Apex engine or a group of Apex engines executes across is expressed, both at design time
* and run time. The Apex deployment system is responsible for deploying Apex models to and the
* context they need the appropriate engines for execution.
*
*
Model registration is carried out by calling the {@code register()} method, which registers the
* policy model and all its constituent containers with the model service. The containers for
* context schemas, events, context albums, tasks, policies, and key information are all registered.
*
*
Once a policy model is composed, the overall structure of the policy model and all its references
* can be validated. During validation of a policy model, the validation checks listed below are
* executed:
*
* - The policy model is validated as an Apex model, which validates the existence, correctness,
* and duplication of all keys in the model as well as validating the key information of the keys,
* see validation in {@link AxModel}
*
- The schemas in the model must be valid, see validation in {@link AxContextSchemas}
*
- The context albums in the model must be valid, see validation in {@link AxContextAlbums}
*
- The tasks in the model must be valid, see validation in {@link AxTasks}
*
- The policies in the model must be valid, see validation in {@link AxPolicies}
*
- The events in the model must be valid, see validation in {@link AxEvents}
*
- The context schemas referred to in each field in every event must exist
*
- The context schemas referred to in every context album must exist
*
- The context schemas referred to in every task input field and output field must exist
*
- The context albums referred to in every task must exist
*
- The context albums referred to in every state must exist
*
- The trigger event referred to in every state must exist
*
- The default task referred to in every state must exist
*
- In a state, an event that triggers a task must contain all the input fields required by that
* task
*
- In a state, an event that is emitted by a task must contain all the output fields produced by
* that task
*
- All tasks referred to by a state must exist
*
- All events referred to on direct state outputs must exist
*
