Document: draft-ietf-modern-problem-framework-03 Reviewer: Joel Halpern Review Date: 2018-02-06 IETF LC End Date: 2018-02-15 IESG Telechat date: 2018-02-22 Summary: This document is ready for publication as an Informational RFC. Major issues: Minor issues: I presume that the lack of description on how to apply controls to semi-restricted or restricted data, particulalry in the distributed data store case, is deliberate? I presume that the WG intent is that this is a topic to be dealt with in the solutions, not the problem statement and framework? Things are fine if that is the intent. If the WG views this as an actual useful description of how to handle those aspects, then I would ask for more descriptions. Nits/editorial comments: Editorial: In the definition of Credential Authority the text uses the phrase "one of more" when I am pretty sure the intent is "one or more".
