Description
Specifies a new inclusive union observation. This represents an observation which is inclusively chosen from a set of named sub-observations. In other words, when this observation is created, you can provide any combination of observations from the given sub-observations. Internally this observation uses Attention so can be slower to evaluate and more difficult to train than other observation types. For this reason it should be used sparingly.
