"Anybody who has a stake in the Scheme standards process - except the members of the Steering Committee - may participate in the ratification vote. In order to register, a potential voter must supply a "Statement of Interest" declaring what his stake is in the outcome of the process. Each voter's statement must be original, must be at least 150 words long, and must actually address the question of what the voter's interest is in the Scheme standard. At the end of the registration period (but before any voting), the list of enrolled voters will be published along with their statements of interest."
