Blocker Description
According to the ASF Source Header and Copyright Notice Policy (http://www.apache.org/legal/src-headers.html), all human-readable Apache-developed files that are included within a distribution must include ASL header text. None of our character set description files or locale definition files (the files under etc/nls/) currently does. These headers need to be added in time for the 4.2.0 release.
Since the above mentioned policy applies to releases distributed after November 1, 2006, this task affects trunk only (and not any already published releases or snapshots).
