The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the [Rendered Value extension](extension-rendered-value.html). Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe."/> <min value="0"/> <max value="1"/> <base> <path value="Identifier.value"/> <min value="0"/> <max value="1"/> </base> <type> <code value="string"/> </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())"/> <xpath value="@value|f:*|h:div"/> <source value="http://hl7.org/fhir/StructureDefinition/Element"/> </constraint> <isModifier value="false"/> <isSummary value="true"/> <mapping> <identity value="v2"/> <map value="CX.1 / EI.1"/> </mapping> <mapping> <identity value="rim"/> <map value="II.extension or II.root if system indicates OID or GUID (Or Role.id.extension or root)"/> </mapping> <mapping> <identity value="servd"/> <map value="./Value"/> </mapping> </element> <element id="Identifier.period"> <path value="Identifier.period"/> <short value="Time period when id is/was valid for use"/> <definition value="Time period during which identifier is/was valid for use."/> <min value="0"/> <max value="1"/> <base> <path value="Identifier.period"/> <min value="0"/> <max value="1"/> </base> <type> <code value="Period"/> </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())"/> <xpath value="@value|f:*|h:div"/> <source value="http://hl7.org/fhir/StructureDefinition/Element"/> </constraint> <isModifier value="false"/> <isSummary value="true"/> <mapping> <identity value="v2"/> <map value="CX.7 + CX.8"/> </mapping> <mapping> <identity value="rim"/> <map value="Role.effectiveTime or implied by context"/> </mapping> <mapping> <identity value="servd"/> <map value="./StartDate and ./EndDate"/> </mapping> </element> <element id="Identifier.assigner"> <path value="Identifier.assigner"/> <short value="Organization that issued id (may be just text)"/> <definition value="Organization that issued/manages the identifier."/> <comment value="The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization."/> <min value="0"/> <max value="1"/> <base> <path value="Identifier.assigner"/> <min value="0"/> <max value="1"/> </base> <type> <code value="Reference"/> <targetProfile value="http://hl7.org/fhir/StructureDefinition/Organization"/> </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())"/> <xpath value="@value|f:*|h:div"/> <source value="http://hl7.org/fhir/StructureDefinition/Element"/> </constraint> <isModifier value="false"/> <isSummary value="true"/> <mapping> <identity value="v2"/> <map value="CX.4 / (CX.4,CX.9,CX.10)"/> </mapping> <mapping> <identity value="rim"/> <map value="II.assigningAuthorityName but note that this is an improper use by the definition of the field.
