Cross-version Extension for R4B.Substance.instance for use in FHIR R5
This cross-version extension represents Substance.instance from http://hl7.org/fhir/StructureDefinition/Substance|4.3.0 for use in FHIR R5.
If this describes a specific package/container of the substance
Substance may be used to describe a kind of substance, or a specific package/container of the substance: an instance.
`Substance.instance` maps to R5 `Substance.instance`. Has no type mapping Changed from an array to a single value (max cardinality from * to 1). So is mapped as SourceIsBroaderThanTarget.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
Identifier associated with the package/container (usually a label affixed directly).
Additional content defined by implementations
May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
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.
Source of the definition for the extension code - a logical name or a URL.
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.
When the substance is no longer valid to use. For some substances, a single arbitrary date is used for expiry.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R5/extensibility.html) for a list).
