dsr21: "may experience an unacceptably high numberof false negatives" - its
not clear what "false negatives" means in this context. I would say "may
frequently treat two XRIs as nonequal when if fact they are equal."
section 22.214.171.124 has a cross reference to section 0 - clearly this is wrong.
Nothing else jumps out at me - though I've focused mostly on changes.
Reviewing old unchanged text tends to be less effective because of my
familiarity with it. Things always slip by - time for more eyes!!!
