Detailed Descriptions for the elements in the extension.
| Extension | |
| Element Id | Extension |
| Definition | The absolute geographic location of the Location, expressed using the WGS84 datum (This is the same co-ordinate system used in KML). |
| Control | 0..1 This element is affected by the following invariants: ele-1 |
| Comments | The extension can be further extended to include unique geolocation identifiers, confidence, altitude, etc. |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (xpath: @value|f:*|h:div) ext-1: Must have either extensions or value[x], not both (xpath: exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])) |
| Extension.id | |
| Element Id | Extension.id |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Control | 0..1 |
| Type | string |
| Extension.extension | |
| Element Id | Extension.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 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. |
| Control | 0..* |
| Type | Extension |
| Alternate Names | extensions, user content |
| 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. |
| Slicing | This element introduces a set of slices. The slicing rules are:
|
| Extension.extension(latitude) | |
| Element Id | Extension.extension:latitude |
| Definition | Latitude. The value domain and the interpretation are the same as for the text of the latitude element in KML (see notes below). |
| Control | 1..1 |
| Type | Extension |
| Extension.extension.id | |
| Element Id | Extension.extension:latitude.id |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Control | 0..1 |
| Type | string |
| Extension.extension.extension | |
| Element Id | Extension.extension:latitude.extension |
| Definition | An Extension |
| Control | 0..0 |
| Type | Extension |
| Slicing | This element introduces a set of slices. The slicing rules are:
|
| Extension.extension.url | |
| Element Id | Extension.extension:latitude.url |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Control | 1..1 |
| Type | uri |
| Comments | 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. |
| Fixed Value | latitude |
| Extension.extension.valueDecimal | |
| Element Id | Extension.extension:latitude.valueDecimal |
| Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
| Control | 0..1 |
| Type | decimal |
| Extension.extension(longitude) | |
| Element Id | Extension.extension:longitude |
| Definition | Longitude. The value domain and the interpretation are the same as for the text of the longitude element in KML (see notes below). |
| Control | 1..1 |
| Type | Extension |
| Extension.extension.id | |
| Element Id | Extension.extension:longitude.id |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Control | 0..1 |
| Type | string |
| Extension.extension.extension | |
| Element Id | Extension.extension:longitude.extension |
| Definition | An Extension |
| Control | 0..0 |
| Type | Extension |
| Slicing | This element introduces a set of slices. The slicing rules are:

| Comments | 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. |
| Fixed Value | longitude |
| Extension.extension.valueDecimal | |
| Element Id | Extension.extension:longitude.valueDecimal |
| Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
| Control | 0..1 |
| Type | decimal |
| Extension.url | |
| Element Id | Extension.url |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Control | 1..1 |
| Type | uri |
| Comments | 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. |
