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.
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).

Element `ElementDefinition.minValue[x]` is mapped to FHIR R4B element `ElementDefinition.minValue[x]` as `RelatedTo`. The mappings for `ElementDefinition.minValue[x]` do not cover the following types: Address, Annotation, Attachment, base64Binary, boolean, code, CodeableConcept, Coding, ContactPoint, HumanName, id, Identifier, markdown, Meta, oid, Period, Range, Ratio, Reference, SampledData, Signature, string, Timing, uri. The target context `ElementDefinition.minValue[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `ElementDefinition`. Except for date/date/instant, the type of the minValue[x] SHALL be the same as the specified type of the element. For the date/dateTime/instant values, the type of minValue[x] SHALL be either the same, or a a [Duration](https://hl7.org/fhir/datatypes.html#duration) which specifies a relative time limit to the current time. The duration value is positive, and is subtracted from the current clock to determine the minimum allowable value. A minimum value for a Quantity is interpreted as an canonical minimum - e.g. you cannot provide 100mg if the minimum value is 10g.

The full length could be stored. In some cases, data might be truncated, though truncation should be undertaken with care and an understanding of the consequences of doing so. If not specified, there is no conformance expectation for length support.

Element `ElementDefinition.mustSupport` is mapped to FHIR R4B element `ElementDefinition.mustSupport` as `Equivalent`. "Something useful" is context dependent and impossible to describe in the base FHIR specification. For this reason, tue mustSupport flag is never set to true by the FHIR specification itself - it is only set to true in profiles. This is done in [Resource Profiles](https://hl7.org/fhir/profiling.ht.html#mustsupport), where the profile labels an element as mustSupport=true. When a profile does this, it SHALL also make clear exactly what kind of "support" is required, as this can mean many things. Note that an element that has the property IsModifier is not necessarily a "key" element (e.g. one of the important elements to make use of the resource), nor is it automatically mustSupport - however both of these things are more likely to be true for IsModifier elements than for other elements.
Allows a profile to set expectations for system capabilities beyond merely respecting cardinality constraints. Element `ElementDefinition.mustSupport` is mapped to FHIR R4B element `ElementDefinition.mustSupport` as `Equivalent`.
If true, implementations that produce or consume resources SHALL provide "support" for the element in some meaningful way. If false, the element may be ignored and not supported.

Element `ElementDefinition.isModifier` is mapped to FHIR R4B element `ElementDefinition.isModifier` as `Equivalent`. Only the definition of an element can set IsModifier true - either the specification itself or where an extension is originally defined. Once set, it cannot be changed in derived profiles. An element/extension that has isModifier=true SHOULD also have a minimum cardinality of 1, so that there is no lack of clarity about what to do if it is missing. If it can be missing, the definition SHALL make the meaning of a missing element clear.
Allows elements to be introduced into a specification that can't safely be ignored by applications that don't recognize them. Element `ElementDefinition.isModifier` is mapped to FHIR R4B element `ElementDefinition.isModifier` as `Equivalent`.
If this modifies the meaning of other elements
If true, the value of this element affects the interpretation of the element or resource that contains it, and the value of the element cannot be ignored. Typically, this is used for status, negation and qualification codes. The effect of this is that the element cannot be ignored by systems: they SHALL either recognize the element and process it, and/or a pre-determination has been made that it is not relevant to their particular system.

If it can be missing, the definition SHALL make the meaning of a missing element clear.

This element is used to reduce the quantity of data returned in searches. Note that servers may pre-cache summarized resources for optimal performance, so servers may not support per-profile use of the isSummary flag.
