Content

Extensions:
elementdefinition-identifier	identifier : External Identifiers associated with this element - these are identifiers that are associated with the concept this element represents.
elementdefinition-question	question : The default/suggested phrasing to use when prompting a human to capture the data element in question form (e.g. In a survey).
elementdefinition-allowedUnits	allowedUnits : Identifies the units of measure in which the element should be captured or expressed.
elementdefinition-maxValueSet	maxValueSet : The maximum allowable value set, for use when the binding strength is 'extensible'. This value set is the value set from which extensions can be taken from.
elementdefinition-minValueSet	minValueSet : 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.
elementdefinition-inheritedExtensibleValueSet	inheritedExtensibleValueSet : 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.
elementdefinition-bindingName	bindingName : A name that can be used for code generation when generating named enumerations for the binding.
elementdefinition-isCommonBinding	isCommonBinding : Whether the binding is used on multiple resources, or only on this resource.
elementdefinition-equivalence	equivalence : The level of equivalence between the element containing the mapping and the element mapped to.
elementdefinition-namespace	namespace : Use this extension to indicate tha the element has an XML namespace different to http://hl7.org/fhir.
elementdefinition-bestpractice	bestpractice : Mark that an invariant represents 'best practice' rule - a rule that implementers may choose to enforce at error level in some or all circumstances.
elementdefinition-selector	selector : A FHIRPath statement that defines whether an element is in the slice.
elementdefinition-translatable	translatable : Whether translations might be expected for this element in resource instances.
