It's an interesting idea --- fundamentally a typeset document is nothing but nested key value pairs where there are: - tags/formatting large --> small, document --> paragraph --> character-level - content which is tagged I find that if one just finds all the "right" packages and uses appropriate markup it mostly "just works", if one then adds a pair of packages: - one which defines all the additional markup beyond the initial author markup as empty commands - a second which redefines all those commands to achieve the formatting
