0. Extension
Definition	DSTU2: `ValueSet.codeSystem.concept` (new:BackboneElement) Optional Extension Element - found in all resources.
Short	DSTU2: Concepts in the code system (new)Optional Extensions Element
Comments	Element `ValueSet.codeSystem.concept` is part of an existing definition because parent element `ValueSet.codeSystem` requires a cross-version extension. Element `ValueSet.codeSystem.concept` has a context of CodeSystem based on following the parent source element upwards and mapping to `CodeSystem`. Element `ValueSet.codeSystem.concept` has a context of ValueSet based on following the parent source element upwards and mapping to `ValueSet`. Element `ValueSet.codeSystem.concept` has no mapping targets in FHIR R5. Typically, this is because the element has been added (is a new element).

2. Extension.extension
Definition	An Extension 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.
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.

Element `ValueSet.codeSystem.concept.designation.value` has no mapping targets in FHIR R5. Typically, this is because the element has been added (is a new element).
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`)
74. Extension.extension:designation.extension:value.id
Definition	Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Short	Unique id for inter-element referencing

XML Format	In the XML format, this property is represented as an attribute.

76. Extension.extension:designation.extension:value.extension
Definition	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.
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.
