Structures

This structure refers to these other structures:

• Message Header for request and response (https://joofio.github.io/obs-cdss-fhir/StructureDefinition/MessageHeaderCDSS)
• Machine Learning Model (https://joofio.github.io/obs-cdss-fhir/StructureDefinition/MLModel)

Slices

This structure defines the following Slices:

• The element Bundle.entry is sliced based on the value of value:name
