        <!--    A single drug only has a single strength (amount of active ingredient).
         However it can be measured in different ways, giving rise to different values
     of what is basically the same underlying strength.
         In these cases the "strength" attribute can repeat.
         This is common with inhalers, where the strength is the amount of ingredient
     found in a spray or puff, but which differs at
         different distances from the nozzle. The effective strength is therefore
     different when the inhaler is used with a spacer device, 
         which changes the distance. Different countries may also chose to measure
     at different standard distances.
         This is a separate concept to presentation vs. concentration strength (which
     are two ways of expressing the same numeric value).
         Concentration strength could be in the example below, in each "strength",
     but is omitted for clarity.
         All these are different from reference strength (a strength in terms of
     a different substance).
