                <h:p>These are the 7 types prescribed by the SI system, together
         with the "dimensionless" type. We intend to be somewhat uncoventional
         and explore enhanced values of "dimensionless", such as "angle".
         This may be heretical, but we find the present system impossible to implement
         in many cases.</h:p>
