extensionAuthorityUsed identifies the authority used for the extensionElement.

Best practice: If metadata extensions to PBCore are assigned to a media item with the element extensionElement, and the terms used are derived from a specific authority or metadata scheme, use extensionAuthorityUsed to identify whose metadata extensions are being used.

extensionAuthorityUsed can only be contained by the element extensionWrap.

Usage: optional, not repeatable.
