0. Extension
Definition	R5: `TriggerDefinition.condition` (new:Expression) Optional Extension Element - found in all resources.
Short	R5: Whether the event triggers (boolean expression) (new)Optional Extensions Element
Comments	Element `TriggerDefinition.condition` has a context of TriggerDefinition based on following the parent source element upwards and mapping to `TriggerDefinition`. Element `TriggerDefinition.condition` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). This element can be only be specified for data type triggers and provides additional semantics for the trigger. The context available within the condition is based on the type of data event. For all events, the current resource will be available as context. In addition, for modification events, the previous resource will also be available. The expression may be inlined, or may be a simple absolute URI, which is a reference to a named expression within a logic library referenced by a library element or extension within the containing resource. If the expression is a FHIR Path expression, it evaluates in the context of a resource of one of the type identified in the data requirement, and may also refer to the variable %previous for delta comparisons on events of type data-changed, data-modified, and data-deleted which will always have the same type.
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.

20. Extension.extension:description.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.

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.
