New issue 1115: how should the OP behave when a claim is requested but not understood
https://bitbucket.org/openid/connect/issues/1115/how-should-the-op-behave-when-a-claim-is

Víctor Herraiz Posada:

Currently the spec. says that any member in a claim request that in not understood should not fail. does the same answer apply  to claim?

For example:

```json
{
  "id_token": {
    "some_unknown_claim": { "essential": true }
  }
}
```

is the final decision about the behaviour an OP responsibility? \(e.g. fail, only omit the claim…\)
