Only documents that are not a revision can be revisioned and only revisioned documents can be promoted.
Note the difference: IsRevision tells you that this document is a revision of another document, so it can be promoted (using Promote method). HasRevision on the other hand means that this document is revisioned - has revisions that can be accessed with the Revisions property.
