Further, the default value can never be changed, or changed in constraints on content models. Defining default values creates many difficulties in implementation (e.g. when is a value missing?). For these reasons, default values are (and should be) used extremely sparingly. No default values are ever defined in the FHIR specification, nor can they be defined in constraints ("profiles") on data types or resources. This element only exists so that default values may be defined in logical models." /> <min value="0" /> <max value="1" /> <base> <path value="ElementDefinition.defaultValue[x]" /> <min value="0" /> <max value="1" /> </base> <type> <code value="base64Binary" /> </type> <type> <code value="boolean" /> </type> <type> <code value="canonical" /> </type> <type> <code value="code" /> </type> <type> <code value="date" /> </type> <type> <code value="dateTime" /> </type> <type> <code value="decimal" /> </type> <type> <code value="id" /> </type> <type> <code value="instant" /> </type> <type> <code value="integer" /> </type> <type> <code value="markdown" /> </type> <type> <code value="oid" /> </type> <type> <code value="positiveInt" /> </type> <type> <code value="string" /> </type> <type> <code value="time" /> </type> <type> <code value="unsignedInt" /> </type> <type> <code value="uri" /> </type> <type> <code value="url" /> </type> <type> <code value="uuid" /> </type> <type> <code value="Address" /> </type> <type> <code value="Age" /> </type> <type> <code value="Annotation" /> </type> <type> <code value="Attachment" /> </type> <type> <code value="CodeableConcept" /> </type> <type> <code value="Coding" /> </type> <type> <code value="ContactPoint" /> </type> <type> <code value="Count" /> </type> <type> <code value="Distance" /> </type> <type> <code value="Duration" /> </type> <type> <code value="HumanName" /> </type> <type> <code value="Identifier" /> </type> <type> <code value="Money" /> </type> <type> <code value="Period" /> </type> <type> <code value="Quantity" /> </type> <type> <code value="Range" /> </type> <type> <code value="Ratio" /> </type> <type> <code value="Reference" /> </type> <type> <code value="SampledData" /> </type> <type> <code value="Signature" /> </type> <type> <code value="Timing" /> </type> <type> <code value="ContactDetail" /> </type> <type> <code value="Contributor" /> </type> <type> <code value="DataRequirement" /> </type> <type> <code value="Expression" /> </type> <type> <code value="ParameterDefinition" /> </type> <type> <code value="RelatedArtifact" /> </type> <type> <code value="TriggerDefinition" /> </type> <type> <code value="UsageContext" /> </type> <type> <code value="Dosage" /> </type> <condition value="eld-15" /> <isModifier value="false" /> <isSummary value="true" /> <mapping> <identity value="rim" /> <map value="N/A (MIF territory)" /> </mapping> </element> </snapshot> </StructureDefinition>
