Criticisms
This is a controversial subject as many people think the license is not compatible with the GPL license because of the obligation to include the Microsoft copyright notice in the program. Others think that WordprocessingML specs are a work in progress and many important aspects are still undocumented, or are defined in a binary only form (e.g. OLE and VBA) and those lack complete documentation. Although Microsoft has pledged to complete the specs, some people fear this will never fully happen given Microsoft's track record in revealing their internal information. Microsoft has also refused so far to submit the format to an independent standard body contrary to the OpenDocument which will be submitted to the ISO standard body.
