Hi Loa,

Thank you for your question and repeating on the list.

"n>=m" - it's a typical use case of m:n protection, but isn't a limitation. I \
apologize for the confusion. I agree with you that could n be lower, equal or higher \
than m in the m:n architecture.

We will incorporate your comments to the next version of this draft.

BR,
Zhenlong
