Hello,   I am the Routing Area Directorate member that was assigned the QA review of draft- ietf-i2rs-security-environment-reqs-01 .   If you’re not familiar with the QA review process please see:  https://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDirDocQa   BR Dave General Comments: - overall the document is organized well and has a good flow leading from overall issues to specific issues and justified requirements. - the document presumes familiarity with the I2RS architecture and states this plainly cuing  the reader to look there first.  That said the document can be read standalone with a conceptual knowledge of the I2RS architecture. See the attached document for marked up and inline comments. Nits - singular / plural usage needs to be consistent - verb plural and tense match need attention Note: I got through page 14.  Many comments earlier in the doc apply to the few remaining sections. Please let me know if you have any questions. Dave Attachment: draft-ietf-i2rs-security-environment-reqs-01.docx Description: draft-ietf-i2rs-security-environment-reqs-01.docx
