ObservationDosageDefinitionPreconditionType

The set of observation type concepts that can be used to express pre-conditions to a particular dosage definition. Rationale: Used to constrain the set of observations to those related to the applicability of a dosage, such as height, weight, age, pregnancy, liver function, kidney function, etc. For example, in drug master-file type records indicating when a specified dose is applicable. OpenIssue: This concept domain should be reviewed to determine whether it needs a "ConceptualSpaceForClassCode" property to link to a RIM classCode.
