There was a recent discussion on standards licenses, and whether or not they should be under the GPL, or under the standard they describe. In my opinion, this should almost never be the case. A standard needs to be under a very flexible license, if a standard does not adapt, it will die. A standard is not a peice of software, and a license like the GPL is not even relative to the purposes of the standard. Also, when a 'bad' standard is released, the author needs to have the ability to update the standard, and force updates into effect without causing massive chaos. Just my 2 cents.
