Definitions for the Extension-Interweave-ValuePrecision extension.
Guidance on how to interpret the contents of this table can be found here.
1. Extension | |
Definition | Explicit precision of the number. This is the number of significant decimal places after the decimal point, irrespective of how many are actually present in the explicitly represented decimal. Optional Extension Element - found in all resources. |
Control | 0..1* |
Comments | The presence of this extension does not change conformance expectations with regard to rendering and calculations that use the number - these are still based on the raw decimal value. Applications that perform calculations SHALL ensure that this extension is removed or updated to the correct precision value if the number is changed. Applications should consider using the exponential form (e.g. 2.10e3) on the raw decimal to manage significant figures, but should be mindful of human display when doing so. |
2. Extension.extension | |
Control | 0..0* |
3. Extension.url | |
Fixed Value | https://fhir.yhcr.nhs.uk/StructureDefinition/Extension-Interweave-ValuePrecision |
4. Extension.value[x] | |
Control | 10..1 |
Type | Choice of: , date, dateTime, Meta, code, string, Address, Attachment, oid, Count, instant, ContactPoint, HumanName, Money, Identifier, Coding, markdown, SampledData, Ratio, id, positiveInt, Age, Distance, Reference, Period, Quantity, Duration, Range, uri, Annotation, boolean, base64Binary, Signature, unsignedInt, time, Timing, decimal, CodeableConcept |
[x] Note | See Choice of Data Types for further information about how to use [x] |

1. Extension | |
Definition | Explicit precision of the number. This is the number of significant decimal places after the decimal point, irrespective of how many are actually present in the explicitly represented decimal. Optional Extension Element - found in all resources. |
Control | 0..1* This element is affected by the following invariants: ele-1 |

Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() | (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
2. Extension.extension | |
Definition | An Extension May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
Control | 0..0* |
Type | Extension |
Alternate Names | extensions, user content |
Comments | 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. |
Slicing | This element introduces a set of slices on Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|
3. Extension.url | |
Definition | Source of the definition for the extension code - a logical name or a URL. |
Control | 1..1 |
Type | uri |
XML Representation | In the XML format, this property is represented as an attribute. |
Comments | 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. |
Fixed Value | https://fhir.yhcr.nhs.uk/StructureDefinition/Extension-Interweave-ValuePrecision |
4. Extension.value[x] | |
Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
Control | 10..1 |
Type | Choice of: integer, date, dateTime, Meta, code, string, Address, Attachment, oid, Count, instant, ContactPoint, HumanName, Money, Identifier, Coding, markdown, SampledData, Ratio, id, positiveInt, Age, Distance, Reference, Period, Quantity, Duration, Range, uri, Annotation, boolean, base64Binary, Signature, unsignedInt, time, Timing, decimal, CodeableConcept |
