IDEAlliance has posted the final program for Extreme Markup Languages this August in Montreal. They've also announced a preconference International Workshop on Markup of Overlapping Structures. "Extreme is the leading international conference on markup theory and practice. If you have interesting markup applications, difficult markup problems, or intriguing solutions to problems related to the design and use of markup, markup languages, or markup tools; if you want to know what the leading theorists of markup are thinking; if you are the house markup expert and want to spend time with your kind, then you should plan on attending Extreme Markup Languages® 2007." Extreme is always a lot of fun, though I won't be able to attend this year myself.
