Extreme Markup Languages is devoted to the theory and practice of markup languages from industrial, academic, and other points of view. It differs from other conferences partly in its unapologetic emphasis on technical subjects and problems on the edges of current practice, and partly in the participants it attracts.

Extreme has a high concentration of markup theorists, computer scientists, linguists, taxonomists, publishers, lexicographers, typographers, software developers, librarians, and other people you want to spend time with. Also anarchists, curmudgeons, and deep thinkers, and a lower than average concentration of managers in need of a clue.

Besides its formal sessions, Extreme has nocturnes (after-hours improvisations by experts on subjects of interest to attendees), posters, and tutorials, and an awesome venue.

Past Conference Proceedings are available.
