purpose:
  v: This extension is part of the cross-version definitions generated to enable use of the element `SubscriptionTopic.canFilterBy` as defined in FHIR R5 in FHIR R4. The source element is defined as: `SubscriptionTopic.canFilterBy` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R5: `SubscriptionTopic.canFilterBy` 0..* `BackboneElement` Following are the generation technical comments: Element `SubscriptionTopic.canFilterBy` is not mapped to FHIR R4, since FHIR R5 `SubscriptionTopic` is not mapped. Element `SubscriptionTopic.canFilterBy` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

  v: URL of the Resource that is the type used in this filter.

  v: Element `SubscriptionTopic.canFilterBy.filterParameter` is part of an existing definition because parent element `SubscriptionTopic.canFilterBy` requires a cross-version extension. Element `SubscriptionTopic.canFilterBy.filterParameter` is not mapped to FHIR R4, since FHIR R5 `SubscriptionTopic` is not mapped. Element `SubscriptionTopic.canFilterBy.filterParameter` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). Chained parameters are allowed (like "patient.gender") - but can not use colons or modifiers.

definition:
  v: 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 manageable, 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.
comment:
  v: 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 `SubscriptionTopic.canFilterBy.modifier` is not mapped to FHIR R4, since FHIR R5 `SubscriptionTopic` is not mapped. Element `SubscriptionTopic.canFilterBy.modifier` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

    v: URL of the Resource that is the type used in this filter. This is the "focus" of the topic (or one of them if there are more than one). It will be the same, a generality, or a specificity of SubscriptionTopic.resourceTrigger.resource or SubscriptionTopic.eventTrigger.resource when they are present.
  comment:
    v: URL of the Resource that is the type used in this filter. Relative URLs are relative to the StructureDefinition root of the implemented FHIR version (e.g., http://hl7.org/fhir/StructureDefinition). For example, "Patient" maps to http://hl7.org/fhir/StructureDefinition/Patient. For more information, see [ElementDefinition.type.code](https://hl7.org/fhir/elementdefinition-definition.html#ElementDefinition.type.code).
