Cross-version Extension for R5.Subscription.filterBy for use in FHIR R4B
This cross-version extension represents Subscription.filterBy from http://hl7.org/fhir/StructureDefinition/Subscription|5.0.0 for use in FHIR R4B.
Criteria for narrowing the subscription topic stream
The filter properties to be applied to narrow the subscription topic stream. When multiple filters are applied, evaluates to true if all the conditions applicable to that resource are met; otherwise it returns false (i.e., logical AND).
`Subscription.filterBy` has no related element in R4B:Subscription
All FHIR elements must have a @value or children unless an empty Parameters resource
hasValue() or (children().count() > id.count()) or $this is Parameters
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
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
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
Allowed Resource (reference to definition) for this Subscription filter
A resource listed in the `SubscriptionTopic` this `Subscription` references (`SubscriptionTopic.canFilterBy.resource`). This element can be used to differentiate filters for topics that include more than one resource type.
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 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.
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.
A type of resource, or a Reference (from all versions)
Filter label defined in SubscriptionTopic
The filter as defined in the `SubscriptionTopic.canFilterBy.filterParameter` element.
eq | ne | gt | lt | ge | le | sa | eb | ap
Comparator applied to this filter parameter.
Search Comparator Codes applied to this filter.
missing | exact | contains | not | text | in | not-in | below | above | type | identifier | of-type | code-text | text-advanced | iterate
Modifier applied to this filter parameter.
Search Modifier Code applied to this filter.
The literal value or resource path as is legal in search - for example, `Patient/123` or `le1950`.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R4B/extensibility.html) for a list).
