I'm wondering if it's the "round tripping" through an external toolchain that isn't the bear here... (X)HTML got a couple of mentions. I would consider those quite clunky to 1) throw through tools, and 2) to sort within anyway. Yes, many of us here appear to have the programming nouse to play with XSLT etc to slice'n'dice a note. The sad thing is we'd probably actually try it. :-) But, seriously, it's not an approach that the general user is going to like much.
