Requirements and design discussion hub

Purpose of this page

This page is to be a central collection point for discussion of requirement issues and design issues. As decisions on the issues are reached, the related discussions should be marked as closed. It is unclear whether this wiki provides a means to enforce such closing. Write-ups of design decisions, which might include pointers to or excerpts from the discussion on these pages, should go into documents which can be uploaded to the Documents page. Source for producing those documents (in whatever form) should go into the git repository.
