0. DV_ORDERED
Definition	Abstract class defining the concept of ordered values, which includes ordinals as well as true quantities. It defines the functions `<` and `_is_strictly_comparable_to()_`, the latter of which must evaluate to `True` for instances being compared with the `<` function, or used as limits in the `DV_INTERVAL\<T>` class. Data value types which are to be used as limits in the `DV_INTERVAL\<T>` class must inherit from this class, and implement the function `_is_strictly_comparable_to()_` to ensure that instances compare meaningfully. For example, instances of `DV_QUANTITY` can only be compared if they measure the same kind of physical quantity. Base definition for all types defined in FHIR type system.
