This structure defines the following Slices:

• The element 2 is sliced based on the values of Observation.meta.security
• The element 3 is sliced based on the values of Observation.identifier
• The element 2 is sliced based on the values of Observation.category
• The element 1 is sliced based on the value of Observation.code.coding
• The element 1 is sliced based on the value of Observation.interpretation.coding
• The element 1 is sliced based on the value of Observation.component
• The element 1 is sliced based on the value of Observation.component.code.coding
• The element 1 is sliced based on the value of Observation.component.value[x]
• The element 1 is sliced based on the value of Observation.component.value[x].coding
