### Tags mittels Enumeration

Wenn Sie eine große Anwendung haben, können sich am Ende **viele Tags** anhäufen, und Sie möchten sicherstellen, dass Sie für verwandte *Pfadoperationen* immer den **gleichen Tag** nehmen.

In diesem Fall macht es Sinn, die Tags in einem `Enum` zu speichern.

    end
    dep ->> operation: Run dependency, e.g. DB session
    opt raise
        operation -->> dep: Raise Exception (e.g. HTTPException)
        opt handle
            dep -->> dep: Can catch exception, raise a new HTTPException, raise other exception
        end
        handler -->> client: HTTP error response
    end

    operation ->> client: Return response to client
