Summary:

This draft is on the right track but has open issues, described in the 
review.

Issues:

Major: 0
Minor: 2
Nits:  3

1) MINOR: Section 4.5, Fig 3

I find this figure confusing. It starts out looking like a sequence 
diagram, where time flows from top to bottom. But then overlayed on it 
is a nested text outline that seems to interact with the sequence 
diagram. Based on the outline numbering I expect the time sequence to be 
2a,2b,3,4. but based on positioning within the sequence diagram it seems 
that the order should be 2a,3,2b,4. I don't understand how this is 
intended to be read.

2) MINOR: Section 6.2.1:

Is any persistent state assumed in this API or is it stateless? If state 
is assumed, I would like to see the state model described.

3) NIT: Section 1: NIT

    TEEs use hardware enforcement combined with software protection to
    secure TAs and its data.

s/its/their/

4) NIT: Section 2: Device User:...

The last sentence is a fragment. Needs to be reworded.

5) NIT: IdNits

IdNits reports a couple of outdated references that need updating.
