This comment confuses me. The auth scheme is included in the challenge:

```
challenge   = auth-scheme 1*SP 1#auth-param
```

and in https://tools.ietf.org/html/rfc2617#section-1.2 :

```
   The realm directive (case-insensitive) is required for all
   authentication schemes that issue a challenge.
```

I think it really depends on how we understand this sentence:
```
The authentication parameter realm is defined for all authentication schemes.
```

1. The defined `realm` can be used for all auth schemes in the challenge.
2. Each auth scheme should be provided with a `realm`.

I regard it as (2). Thoughts?
