The official ballot to approve DocBook V5.0 as an OASIS standard closed on October 31st, and the standard was approved with a healthy margin.
Congratulations to Norm Walsh for driving the process and keeping the rest of us on the Technical Committee focused and moving in the right direction. His contribution to DocBook in general and DocBook V5.0 in particular is incalculable.
O’Reilly Media will publish DocBook: The Definitive Guide–Second Edition in collaboration with XML Press. The second edition, which is authored by Norm Walsh, will be the official reference for DocBook V5.0.
