0. Extension
Definition	R4B: `ImplementationGuide.definition` (new:BackboneElement) Optional Extension Element - found in all resources.
Short	R4B: Information needed to build the IG (new)Optional Extensions Element
Comments	Element `ImplementationGuide.definition` has a context of ImplementationGuide based on following the parent source element upwards and mapping to `ImplementationGuide`. Element `ImplementationGuide.definition` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). Principally, this consists of information abuot source resource and file locations, and build parameters and templates.
Control	0..1* 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.

While the target element `ImplementationGuide.package.resource.source[x]` is a choice type and does not allow extensions, the `alternate-reference` extension can be applied to Reference values within it. Usually this is a relative URL that locates the resource within the implementation guide. If you authoring an implementation guide, and will publish it using the FHIR publication tooling, use a URI that may point to a resource, or to one of various alternative representations (e.g. spreadsheet). The tooling will convert this when it publishes it.
