Allow DV_QUANTITY, qualified real property values with no units.

Description

There's a requirement to model scales - e.g. pain scales - in the clinical domain using DV_QUANTITY with a 'qualified real' property, but where units do not seem appropriate. So in this case, it would be modelled with a real and no units or blank unit.

However, the openEHR specification requires all DV_QUANTITY to have units and the units must not be blank, which will not meet the above requirement.
