Microsoft OOXML Rejected
OOXML stands for Office Open XML. PC users who used Microsoft Office 2007 should familiar with this as it is the default file format. Recently, Microsoft has tried to get OOXML standardize by ISO.
Although, at the first round Microsoft successfully to get 74% support from the voting members. But only 53% of the voting P-members support it. To win it, one should get 2/3 of the votes. Many national bodies have also voted against this standard. The reasons are due to the date format, languages support and compatibility to the existing standard.
More disadvantages of the OOXML is because of the cost. Competitors like openoffice.org offer the same feature on document formats and also are free.
