Doesn't that make it possible for copyright holders to make it difficult for the IETF to update older standards? Let's consider if company X participated as editor, or merely a major contributor, to document Y five years ago. Today competitor Z is critically dependent on this technology. Company X no longer builds products using Y technology. I could see how company X would not see any point in granting Z any rights to update the IETF standard in this situation. To update Y you will need to rewrite the entire document, to avoid copyright tainting. This seems like a serious problem with the new policy to me. /Simon _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
