It seems like Microsoft, whom have promised the world that they would use the standard approved version of OOXML in it's future products have failed for 2 years up till now. Office 2010, is said to still use the unapproved version of OOXML rather than the approved version of OOXML.
Microsoft really needs to follow as they have promised rather then making empty promises that gives it more bad names and maybe even more lawsuits to face ? Microsoft... why can't you just stop your nonsense and follow the standards, follow the world, follow the correct path to take ? Stop making really stupid and foolish mistakes !!!!
