Microsoft votes to add ODF to ANSI standards list

RzUpAnmsCwrds writes: "In a puzzling move, Microsoft today voted to support the addition of the OpenDocument file formats to the American National Standards List. OpenDocument is used by many free-software office suites, including OpenOffice.org. Microsoft is still pushing its own Office Open XML format, which it hopes will also become an ANSI standard. Is Microsoft serious about supporting ODF, or is this a merely a PR stunt to make Office Open XML look more like a legitimate standard?"
