External Identifiers associated with this element - these are identifiers that are associated with the concept this element represents.

The default/suggested phrasing to use when prompting a human to capture the data element in question form (e.g. In a survey).

Identifies the units of measure in which the element should be captured or expressed.

This acts as an overall 'required' binding for an element that already has a less restrictive binding. It is used when there is a desire to have a 'small' enumerable binding that meets most needs and where the overall value set that the codes must be drawn from is 'infinite'. The the base less restrictive binding SHALL be a proper subset of the max binding valueset. In most cases, this extension is used where the base binding is 'extensible'.

The minimum allowable value set, for use when the binding strength is 'required' or 'extensible'. This value set is the minimum value set that any conformant system SHALL support.

A reference to an extensible value set specified in a parent profie in order to allow a conformance checking tool to validate that a code not in the extensible value set of the profile is not violating rules defined by parent profile bindings.

A name that can be used for code generation when generating named enumerations for the binding.

Whether the binding is used on multiple resources, or only on this resource.

The level of equivalence between the element containing the mapping and the element mapped to.

Use this extension to indicate tha the element has an XML namespace different to http://hl7.org/fhir. The special value noNamespace indicates that there is no assigned XML namespace.

Mark that an invariant represents 'best practice' rule - a rule that implementers may choose to enforce at error level in some or all circumstances.

Explains why an invariant is labelled as a best practice invariant.

A FHIRPath statement that defines whether an element is in the slice.

Whether translations might be expected for this element in resource instances.

The specific element to use in the referenced profile. This is used when a backbone element is being profiled, rather than an established type.

A pattern that all the target resources follow - that is, a pattern that they all declare their relationship to.

If true indicates that the specified type, profile or targetProfile must be supported by implementations.

The default type that applies if the instance doesn't specify a particular type, and there is a choice of types.

This extension references a ConceptMap that maps to relevant terminologies used in an implementation.

Will cause a GraphDefinition to be executed and the referred-to instance be considered "valid" for that GraphDefinition if the instance is the start of a result of executing that GraphDefinition.

If the extension is present on one of the named properties in a differential, the element property should be removed from the the corresponding snapshot.element during snapshot generation.
