Detailed Descriptions for the elements in the extension.
Extension | |
Element Id | Extension |
Definition | Workflow Status is used to represent details of the value set development process while the value set has an Activity Status of Preliminary. The development of a value set often follows a formal workflow process from initiation to completion, and this element carries the state variable for this state machine. The assumption is that when first created a value set would have a workflow state of Draft. Additional workflow states may be used. |
Control | 0..1 This element is affected by the following invariants: ele-1 |
Comments | The values that this element may assume include phrases that capture various stages in review and approval. In addition to the minimum of ???Draft???, these include ???Proposed???, ???Approved???, ???Ready to Publish???. There may be additional states defined by different developers. This is an optional element because the use of Activity Status ???Preliminary??? may be sufficient for some implementations. |
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 | An Extension |
Control | 0..0 |

Slicing | This element introduces a set of slices. The slicing rules are:
|
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. |
Fixed Value | http://hl7.org/fhir/StructureDefinition/codesystem-workflowStatus |
Extension.valueString | |
Element Id | Extension.valueString |
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). |
