    <!-- Instructions:
This is a composite process that includes all data acquisitions and data computations involved in a single Observation. 
1. If ObservationCollection is a model computation, acquisitionComponent is not defined
2. Input parameters for the model or measurement are not listed here, they are in ObservationCollection
3. ProcessCapability items are all-inclusive... everything that included computationComponents can potentially produce are listed here
