clarify declarative statements

[Xavier Vilajosana]

• Section 3.4

1. There are a bunch of declarative statements in this section (e.g., "The radio of the RX node is turned on tsRxWait/2..."). Do these need to be re-worded with 2119 keywords?

TW> IMO, no. These are describing the IEEE802.15.4e TSCH operation, rather TW> than specifying something new. Yes, an implementation must follow these TW> rules, but these rules are dictated by IEEE802.15.4e TSCH, no by TW> draft-ietf-6tisch-minimal-12. TW> @AD, we welcome your input/recommendation.
