Extension glstring - Detailed Descriptions

Detailed Descriptions for the elements in the extension.

Extension
Element Id Extension
Definition

glstring.

Cardinality 0..1 This element is affected by the following invariants: ele-1
Invariants
Inherited by this element
ele-1 Rule All FHIR elements must have a @value or children hasValue() or (children().count() > id.count())
ext-1 Rule Must have either extensions or value[x], not both extension.exists() != value.exists()
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.

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.

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.

ele-1 Rule All FHIR elements must have a @value or children hasValue() or (children().count() > id.count())
ext-1 Rule Must have either extensions or value[x], not both extension.exists() != value.exists()
Slicing This element introduces a set of slices. The slicing rules are:
  • unordered
  • Open
  • discriminators: value:url
Extension.extension(url)
Element Id Extension.extension:url
Definition

glstring using a URI reference.

Extension.extension.id
Element Id Extension.extension:url.id
Definition

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Extension.extension.extension

Slicing This element introduces a set of slices. The slicing rules are:
  • unordered

Extension.extension.url
Element Id Extension.extension:url.url
Definition

Source of the definition for the extension code - a logical name or a URL.

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 url
Extension.extension.value[x]
Element Id Extension.extension:url.value[x]
Definition

Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
