In Service Software Upgrade Draft

Hello BMWG,
	The ISSU draft is in a pretty solid state, from the authors point of
view. We wanted to solicit a bit of feedback, and make sure we've covered
all bases. There was some discussion around the authors as to adding some
text around timers and counters in the draft - do you trust the DUT?
Should you confirm these outside of the DUT? Etc. Thoughts?

Kind regards,
Sarah & Fernando & Gery
