I consider this is a good document.
> profiles to establish conformance levels
I consider that this would be a good idea!
Of course, just writing that it is good does not help to improve it.
Therefore, I will try to describe a detail that could be clarified.
On page 5: "import conformance [...] in the form provided by another repository"
On page 6: "export conformance [...] in an agreed-upon form"
Maybe, the "other repository" is not required to be PREMISS-conformant.
Nonetheless, I consider that the reasons for what seems to be a
non-symmetry could be clarified.
