Hi Folks, I have produced yet another revision of DR 349 concerning Clarification of UII Format attribute type and tag-bases object classes. It may be found on http://www.x500standard.com/uploads/Ig/DR_349Rev3.pdf It will certainly not be the final revision, as there still are many unanswered questions.
