Re: Even Microsoft doesn't use OOXML 14 December 2011 19:42

Microsoft implement the Transitional variant of OOXML, but doesn't
fully support the Strict version. They are still planning to support
read/write in Strict in the next major release of Office. See
http://en.wikipedia.org/wiki/Office_Open_XML for more details about
the Transitional and Strict forms.
