"A bare key must be non-empty."

[Diggsey]

The docs say there's only one way to define a key, so what is a "bare" key?

Hi! This is due to a cleanup error in an early version of the spec. Previously we had in mind to support defining keys with quotes, then we opted to be consistent with the "one way of doing things" idea and left only one way to define a key. The bare key concept no longer exists and the specs document has just been fixed, both in this repository and on the main page.

Thanks for the feedback!
