"r" is a value for very few individuals in the Braun Blanquet cover abundance scale which is used a lot in vegetation studies. It is like various others a non continous scale with discrete values. I do not think we should restrict quantity to contious numeric scales. Markus

Markus can probably answer this question:
What would be the expected value of QuantityType for a Quantity of "r"?
A comment Bob Morris occasionally makes is: "1 is greater than 2 for sufficently large values of 1". If some particular quantity type has a standard set of codes that represent numbers, then it might be appropriate to use those standard codes as values of quantity.

'quantity' usually implies an amount, encoded as a scaled number. In most other domains it does not include a value from an enumerated set. The latter may be called 'quality'. Both quantity and quality are subclasses of 'property'.
