Common DrugClass mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

01
Brand names in drug members
Wrong
```
drug: Lipitor, Crestor (brand names)
```
Right
```
Use nonProprietaryName for the generic; proprietaryName for brand
```
Drug classes are generic concepts; listing brand names limits the class to one manufacturer.
