 * 
 * <p>
 * The difference between dimensional models lies in the assumptions each makes and, in consequence,the operations each permits. For example, the
 * summation of a {@link javax.measure.quantity.Length length} and a {@link javax.measure.quantity.Time time} is not allowed by the standard model,
 * but is quite valid in a relativistic context.
