I Don't Believe in Imaginary Property writes "The rumors of a fourth OOXML complaint turned out to be true. Denmark has become the fourth nation to protest the ISO's acceptance of OOXML, and Groklaw has a translation of their complaint. They now join India, Brazil, and South Africa. There are going to be plenty of questions about deadlines, because people have been given two different deadlines for appeals, and the final DIS of OOXML was late in being distributed and not widely available. In fact, that seems to be one of Denmark's complaints, along with missing XML schemas, contradictory wording, lack of interoperability, and troubles with the maintenance of DIS29500. In other words, we should expect a lot of wrangling over untested rules from here on out, and Microsoft knows how to deal with that."
