From that post there were responses in favor of the use of Markdown formatting and suggestions to not use mathml within a draft targeting an RFC specification and suggestions to update a few urls. I propose to proceed with a format conversion of the FFV1 specification from lyx to Markdown and then I'll file tickets or patches to explore simplifying the mathml expressions and updating the urls. Attached is a patch to convert the formatting (but not meaning) of the FFV1 specification from lyx to markdown.
