Semantics of an empty publish JWT claim

[Blacksmoke16]

https://mercure.rocks/spec#publishers calls out that:

If mercure.publish is not defined, or contains an empty array, then the publisher MUST NOT be authorized to dispatch any update.

However the last line within the https://mercure.rocks/docs/getting-started#publishing section says:

The JWT must contain a publish property containing an array of topic selectors. This array can be empty to allow publishing anonymous updates only. The topic selector * can be used to allow publishing private updates for all topics.

Which one is correct?
