A profile describing base requirements for all primary physical activity observations.
This generic profile sets the common expectations that will be inherited by all of the observation profiles in this IG. It is not intended to be implemented directly.
Usage:
Description of Profiles, Differentials, Snapshots and how the different presentations work.
