The example in http://openid.net/specs/openid-connect-core-1_0.html#UserInfoError is incorrect. It has:

```
#!text

  HTTP/1.1 401 Unauthorized
  WWW-Authenticate: error="invalid_token",
    error_description="The Access Token expired"
```

but should be:

```
#!text

  HTTP/1.1 401 Unauthorized
  WWW-Authenticate: Bearer error="invalid_token",
    error_description="The Access Token expired"
```
