What's the "B" Level in Protocols?

[zigzig]

Sorry if this has been discussed elsewhere. I've seen a few elements that have "B" as a level. What does this mean?

Thanks!

It's new this year -- "Basic" level.

An element needed two features for level 2, three for level 3, four for level 4.
It used to be that level 1 meant either one feature or no features. Finally they decided to make a distinction.

So one feature is level 1, and no features but the element meets the definition of the element is Basic level (B).

Hm, interesting. Thank you!
