I agreed with Benjamin's point, so I will change the paragraph for 
clarification. Please refer to my answers for Benjamin's DISCUSS and COMMENTS.

I will get rid of the "SHALL".

I will change "MAY" with "are". And I will check the others as well.

I don’t get your point about 3), but IPv6 over NFC is a just protocol and can 
be used for every NFC-enabled device (including IP-Gateway devices), which are 
connected to the Internet.
