[Taps] IMPORTANT IETF pre-work

While [the mindset 
doc](https://www.ietf.org/internet-drafts/draft-gjessing-taps-minset-04.txt) 
isn’t final (there are a few TBDs), it is mostly complete. As it is 
one of our deliverables it needs a thorough review.  Please come to the 
wg meeting prepared to discuss whether you think the document is ready 
for wg last call and, if not, what your concerns are.

Thanks,

—aaron
