Public Domain Notices

We're run into an issue on the ICU project. Some of the code files contain public domain notices, such as tzfile.h /* ** This file is in the public domain, so clarified as of ** 1996-06-05 by Arthur David Olson. */ However, other files, like zic.c are missing that notice. It is our impression that the goal was for all the code to be public domain. What we'd request is: a) an email stating that it is the intention for all the files to be public domain. b) in the next release of the code, for all the files to contain a public domain notice. (If this isn't possible, there are just 2 that we really need it to be on.) Mark
