"The DoW agrees with these principles, reflects them in law and policy, and we put them into our agreement" is incredibly wishy washy.

What does it even mean to reflect those principles in law? Did they pass a law that says they can't do it? Which one?

What does it mean to "put them into our agreement"? Did they just have a section in the appendix listing various principles, or is there agreement from both parties to not violate those principles? What system does the contract specify for verification of compliance?
