Proposed Disposition of DIS 29500 Comment GB-0010 (Modified: 2007-10-27) The document “Office Open XML Overview” was intended to provide some background and contextual information about OOXML for reviewers during both the Ecma adoption stage and the 5-month Ballot stage of the Fast-Track process. (Such a document is often referred to as a white paper.) As such, this document will not be included in the published standard.
