Interesting developments on the documentation front. I can now look at integrating either one of these books into the OpenLink Online Documentation database (which is XML, RSS, and OPML in action), but more importantly help to spread the good work of these authors, which will potentially generate revenue for them on a variety of fronts (the good work isn't going to be in vain).
XForms Freebie First Eric van der Vlist makes his RELAX NG book freely available, and now Micah Dubinko has done the same re XForms.
RELAX NG is a book in progress written by Eric van der Vlist for O'Reilly and submitted to an open review process. The result of this work will be freely available on the World Wide Web under a Free Documentation Licence (FDL).
The subject of this book, RELAX NG (http://relaxng.org), is a XML schema language developped by the OASIS RELAX NG Technical Committee and recently accepted as Draft International Standard 19757-2 by the Document Description and Processing Languages subcommittee (DSDL) of the ISO/IEC Joint Technical Committee 1 (ISO/IEC JTC 1/SC 34/WG 1).
