Huge upvote on this, for whatever that's worth (and with apologies for resurrecting an old thread).
I've been looking for a way to get from Markdown to paragraph-styled documents for further formatting, and it doesn't seem possible. I'd settle for just heading paras being tagged with the appropriate style in Word or Pages and everything else coming in as 'Body Text', though ordered and unordered lists and URL links would be useful too.
Without some way of doing this, documents ultimately bound for typesetting more-or-less have to start in Word or Pages. Yuck. I suspect the likely solution is for Pages to acquire some sort of HTML import filter, but I'm not holding out much hope.
(meanwhile: huge thanks for Marked, Brett. I'm a very happy customer, just a demanding one. :-)
I have found a solution if you are using Nisus Writer Pro. There is a markdown conversion macro in the Nisus forums ( http://nisus.com/forum/viewtopic.php?f=18&t=4013 ) that converts Markdown and applies RTF styles in the process. Of course this bypasses Marked altogether.
Texts does preserve styles when you export markdown to Word, so it should be possible.
My workaround is to build an index page in Marked and save that as a .md fie, then use Texts to export to Word. However, the MMD metadata placed in the body only shows as variables (%name), so it's not a perfect solution.
