It's been a really long time since I looked at this kind of stuff in any detail. The librarians I worked with at university would go on and on about semantic markup, and there were some very dedicated users that seemed to be willing to slog through the SGML nightmare. But, as soon as HTML came out it swamped the other technologies because it was so easy for people.
Has anything changed since the SGML days? Rhetorically, it all still sounds like a bunch of librarians complaining woefully that they can't do search properly if no one marks up their data properly.
