The Working Group has published its Initial Report that contains its discussion and put the arguments it has gathered to the community. The report provides both detailed arguments in favour and opposing mandatory transformation and indicates that a majority of the Working Group currently favours not to recommend mandatory transformation and/or transliteration of Contact Information. The Working Group hopes that community feedback will maximise its consensus level for the Final Report and, therefore, its members strongly encourage the Community to provide additional arguments in favour/opposing mandatory transformation of contact information data further to facilitate the WG's consensus building process.
