Observation Schema

This object allows you to construct a description of the kind of observations you might want to provide as input to a policy. Internally this object contains a pool of individual elements. This allows them to be constructed performantly and in a cache efficient way. This object is therefore required to access any data about the individual observation elements that are created.
