Integer numbers are discrete, the set of integers is infinite but countable. No arbitrary limit is imposed on the range of integer numbers. Two NULL flavors are defined for the positive and negative infinity."/> <fhirVersion value="5.0.0"/> <kind value="primitive-type"/> <abstract value="false"/> <type value="integer"/> <baseDefinition value="http://hl7.org/fhir/StructureDefinition/integer"/> <derivation value="constraint"/> <snapshot> <extension url="http://hl7.org/fhir/tools/StructureDefinition/snapshot-base-version"> <valueString value="5.0.0"/> </extension> <element id="integer"> <path value="integer"/> <short value="Primitive Type integer"/> <definition value="A whole number"/> <comment value="32 bit number; for values larger than this, use decimal"/> <min value="0"/> <max value="*"/> <base> <path value="integer"/> <min value="0"/> <max value="*"/> </base> <constraint> <key value="ele-1"/> <severity value="error"/> <human value="All FHIR elements must have a @value or children"/> <expression value="hasValue() or (children().count() > id.count())"/> <source value="http://hl7.org/fhir/StructureDefinition/Element"/> </constraint> <isModifier value="false"/> <isSummary value="false"/> </element> <element id="integer.id"> <path value="integer.id"/> <representation value="xmlAttr"/> <short value="xml:id (or equivalent in JSON)"/> <definition value="unique id for the element within a resource (for internal references)"/> <min value="0"/> <max value="0"/> <base> <path value="Element.id"/> <min value="0"/> <max value="1"/> </base> <type> <extension url="http://hl7.org/fhir/StructureDefinition/structuredefinition-fhir-type"> <valueUrl value="string"/> </extension> <code value="http://hl7.org/fhirpath/System.String"/> </type> <isModifier value="false"/> <isSummary value="false"/> </element> <element id="integer.extension"> <path value="integer.extension"/> <short value="Extension"/> <definition value="An Extension"/> <min value="0"/> <max value="0"/> <base> <path value="Element.extension"/> <min value="0"/> <max value="*"/> </base> <type> <code value="Extension"/> </type> <constraint> <key value="ele-1"/> <severity value="error"/> <human value="All FHIR elements must have a @value or children"/> <expression value="hasValue() or (children().count() > id.count())"/> <source value="http://hl7.org/fhir/StructureDefinition/Element"/> </constraint> <constraint> <key value="ext-1"/> <severity value="error"/> <human value="Must have either extensions or value[x], not both"/> <expression value="extension.exists() != value.exists()"/> <source value="http://hl7.org/fhir/StructureDefinition/Extension"/> </constraint> <isModifier value="false"/> <isSummary value="false"/> </element> <element id="integer.value"> <path value="integer.value"/> <representation value="xmlAttr"/> <short value="Primitive value for integer"/> <definition value="The actual value"/> <min value="0"/> <max value="1"/> <base> <path value="integer.value"/> <min value="0"/> <max value="1"/> </base> <type> <extension url="http://hl7.org/fhir/StructureDefinition/structuredefinition-fhir-type"> <valueUrl value="integer"/> </extension> <extension url="http://hl7.org/fhir/StructureDefinition/regex"> <valueString value="[0]|[-+]?[1-9][0-9]*"/> </extension> <code value="http://hl7.org/fhirpath/System.Integer"/> </type> <minValueInteger value="-2147483648"/> <maxValueInteger value="2147483647"/> <isModifier value="false"/> <isSummary value="false"/> </element> </snapshot> <differential> <element id="integer.id"> <path value="integer.id"/> <max value="0"/> </element> <element id="integer.extension"> <path value="integer.extension"/> <max value="0"/> </element> </differential> </StructureDefinition>
