0. Extension
Definition	R4B: `NutritionProduct.ingredient` (new:BackboneElement) Optional Extension Element - found in all resources.
Short	R4B: Ingredients contained in this product (new)Optional Extensions Element
Comments	Element `NutritionProduct.ingredient` is not mapped to FHIR STU3, since FHIR R4B `NutritionProduct` is not mapped. Element `NutritionProduct.ingredient` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).
Control	0..* This element is affected by the following invariants: ele-1
Is Modifier	false
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() \| (children().count() > id.count())`) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) ele-1: All FHIR elements must have a @value or children (hasValue() \| (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. In order to make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	ExtensionAdditional Content defined by implementations
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Slicing	This element introduces a set of slices on `Extension.extension`. The slices areUnordered and Open, and can be differentiated using the following discriminators: value @ url
4. Extension.extension:item
Slice Name	item
Definition	R4B: `NutritionProduct.ingredient.item` (new:CodeableReference(NutritionProduct))
Short	R4B: The ingredient contained in the product (new)Additional Content defined by implementations
Comments	Element `NutritionProduct.ingredient.item` is part of an existing definition because parent element `NutritionProduct.ingredient` requires a cross-version extension. Element `NutritionProduct.ingredient.item` is not mapped to FHIR STU3, since FHIR R4B `NutritionProduct` is not mapped. Element `NutritionProduct.ingredient.item` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).

Primitive Value	This primitive element may be present, or absent, or replaced by an extension
XML Format	In the XML format, this property is represented as an attribute.
36. Extension.extension:item.extension:reference.extension
Definition	May be used to represent additional information that is not part of the basic definition of the element. In order to make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	Additional Content defined by implementations
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Definition	Source of the definition for the extension code - a logical name or a URL.
Short	identifies the meaning of the extension
Comments	The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.

46. Extension.extension:amount
Slice Name	amount
Definition	R4B: `NutritionProduct.ingredient.amount` (new:Ratio)
Short	R4B: The amount of ingredient that is in the product (new)
Comments	Element `NutritionProduct.ingredient.amount` is part of an existing definition because parent element `NutritionProduct.ingredient` requires a cross-version extension. Element `NutritionProduct.ingredient.amount` is not mapped to FHIR STU3, since FHIR R4B `NutritionProduct` is not mapped. Element `NutritionProduct.ingredient.amount` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).
