0. Extension
Definition	Thời hạn lưu trữ bắt buộc của log audit liên quan đến vi phạm DLCN. Căn cứ: NĐ 356/2025/NĐ-CP Điều 29 khoản 1 điểm c — 'Tổ chức phải lưu hồ sơ vi phạm trong thời gian tối thiểu 5 năm kể từ ngày khắc phục xong sự cố' (đối với dữ liệu vị trí + sinh trắc học). Đặt extension này trên AuditEvent để ghi nhận điểm bắt đầu retention period (typically từ ngày khắc phục xong sự cố vi phạm) và end date dự kiến. Khuyến nghị mặc định 5 năm cho mọi loại DLCN nhạy cảm; có thể dài hơn nếu doanh nghiệp/quy chế nội bộ yêu cầu. Optional Extension Element - found in all resources.
Short	Thời hạn lưu trữ log audit — VN Audit Retention PeriodOptional Extensions Element
Control	0..* This element is affected by the following invariants: ele-1
Is Modifier	false
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) 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. 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 can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	ExtensionAdditional content defined by implementations
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.
Control	0..0*
Type	Extension
Is Modifier	false
Summary	false
Alternate Names	extensions, user content
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
Slicing	This element introduces a set of slices on `Extension.extension`. The slices areUnordered and Open, and can be differentiated using the following discriminators: value @ url
4. Extension.url
Definition	Source of the definition for the extension code - a logical name or a URL.
Short	identifies the meaning of the extension
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.
Control	1..1
Type	uri
Is Modifier	false
XML Format	In the XML format, this property is represented as an attribute.
Summary	false

6. Extension.value[x]
Definition	Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
Short	Period với start = ngày khắc phục, end = start + tối thiểu 5 nămValue of extension
Control	0..1
Type	Period, date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, Coding, SampledData, id, positiveInt, Distance, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, CodeableConcept, ParameterDefinition, dateTime, code, string, Contributor, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, Signature, unsignedInt, time

Is Modifier	false
Summary	false
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
8. Extension.value[x].start
Definition	The start of the period. The boundary is inclusive.
Short	Ngày bắt đầu retention (thường = ngày khắc phục xong sự cố)Starting time with inclusive boundary
Comments	If the low element is missing, the meaning is that the low boundary is not known.
Control	10..1 This element is affected by the following invariants: per-1
Type	dateTime
Is Modifier	false
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Summary	true
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
10. Extension.value[x].end
Definition	The end of the period. If the end of the period is missing, it means no end was known or planned at the time the instance was created. The start may be in the past, and the end date in the future, which means that period is expected/planned to end at that time.
Short	Ngày dự kiến kết thúc retention (≥ start + 5 năm theo NĐ 356 Điều 29)End time with inclusive boundary, if not ongoing
Comments	The high value includes any matching date/time. i.e. 2012-02-03T10:00:00 is in a period that has an end value of 2012-02-03.
Control	0..1 This element is affected by the following invariants: per-1
