  - `name` string — Identifier. Resource name of this taxonomy in URL format. Note: Policy tag manager generates unique taxonomy IDs.
  - `displayName` string — Required. User-defined name of this taxonomy. The name can't start or end with spaces, must contain only Unicode letters, numbers, underscores, dashes, and spaces, and be at most 200 bytes long when encoded in UTF-8. The taxonomy display name must be unique within an organization.
