### Description

The example in this article creates confusion because of mixing custom policy provider and `IAuthrizationRequirementData`.
There's no explanation of how framework actually behaves.

It's not needed to inherit from `Authorize` attribute.
If attribute implements `IAuthrizationRequirementData`, either _active_ policy will be extended with the requirements `IAuthrizationRequirementData` yields, or new policy will be created dynamically.
