After revocation, something has been officially taken away. You might protest the revocation of your car privilege if your parents take it away because you hit the mailbox again.
Revocation refers to the cancelling or annulment of something by some authority. When revocation happens, a privilege, title, or status is removed from someone. If the library revokes your library card, you can no longer take out library books — that's a type of revocation. If a restaurant is dirty, that could result in the revocation of its health license. If a lawyer breaks the law, it could lead to the revocation of his license to practice law.
