So why point 3. is important? Mainly because there is a strong risk of
lock-in for adopters when it does not work on a consensus. And this is bad.
It might not be bad _now_, but it can become in the future is some
organization feel that they are locked in. After that, they won't want to
engage in any non-officialized-ISO-like format.

Also note that consensus does not mean that everything is accepted if a
majority agrees. The charter can define the target and the raison d'etre of
a format as well as a set of criteria (or an algo) to evaluate the
relevance of requested changes. So it we say, for example, that the raison
d'=EAtre of GTFS is publishing data, any request to ease internal operation
of agencies should not be accepted from the beginning while request to
improve fare calculation for trip planning would be evaluated. (that's a
little black and white, but I hope everybody gets it.)
