The following links will take you directly to some of the most-viewed articles on the Open XML Developer web site. Note that the Open XML schemas and namespace references have changed since some of these articles were posted (due the the Ecma standardization process), so older articles may require a few minor changes in order to work with the current version of the spec. If you have any questions, post them on the Forums section of the site.
