So here are some "Key Messages" from Microsoft's standards team circa 2003 (doing battle with the Australian parliament no doubt) [Emphasis added]:

• An open standard is a publicly available specification which details certain technical functionality that may be implemented in different products and services.  It is adopted in an open, consensus-based process and must satisfy other criteria for transparency, ease of access, and broad implementation as described below.



• Open standards exist to facilitate interoperability and data exchange across various products and services in a marketplace of multiple, competing implementations, while ensuring that certain minimum requirements are met.



• Other types of standards (e.g., “proprietary standards”) and market-based mechanisms exist and are currently used to facilitate interoperability.  However, open standards ensure the highest level of interoperability across the widest range of competing products and services.

I had read the essay by Jon Bosak (SUN Microsystems) on why SUN voted as it did in the US. He lays out a very different strategy. His view is that the battle is lost to completely reject OOXML as an ISO standard. ISO can only reject it with comments, and that is equivalent to giving Microsoft a todo-list on how to fix the draft so as to get it approved. Microsoft has sufficient manpower to easily tackle that.

Most of us had missed what Mr. Bosak saw: OOXML promises interoperability with earlier closed binary formats (the Word Doc, older Excel file formats etc.). But it doesn’t deliver. How on earth could someone be able to convert old binary files to the new format without having the specification of the old formats and a mapping to OOXML. If you are to translate some text from Chinese to English, it doesn’t much help to only know English.
