MS made it open because...

> More than a year after being asked by the European Union to standardize their Office 2003 XML formats, Microsoft submitted 2,000 pages of documentation for a new file format to the Ecma International consortium for it to be made into an open standard. [1]

The competing OpenDocument Format was standardized first though [2].
