I'm not sure what you're asking. Ideally, I'd like to see three things:
(1) A concise description of the technical conflict that needs to be resolved. (2) Good background material for understanding any subtle issues underlying the conflict. (3) A concise, specific and unambiguous proposal for dealing with the conflict. It looks to me as if you've put quite a lot of effort into (2). However, I'm not at all certain I know what obstacle you are running into, and I've some uncertainties about what you are proposing. Have you talked to the di people about this issue? Have they raised any objections? If so, what are they? (We should get involved if you feel that they are making a choice which is technically incorrect and which you can't resolve directly.)
