All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
唯一可識別ID，以供資料項目間相互參照。
resource中資料項目的唯一ID（用於內部參照）。這可以是任何不含空格的字串。
Extensions are always sliced by (at least) url
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
擴充的資料項目之定義連結—一個邏輯名稱或URL
此定義可直接指向可計算的或人類可讀的擴充資料項目的定義，也可以是其他規範中聲明的邏輯URI。此定義**必須（SHALL）** 定義擴充的結構定義的URI。
擴充的資料項目的內容值—必須是一組受限制的data type中的一個（清單請見[Extensibility](http://hl7.org/fhir/2021Mar/extensibility.html)）
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Additional content defined by implementations
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.
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.
A reference to a code defined by a terminology system.
Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.
Allows for alternative encodings within a code system, and translations to other code systems.

Plain text representation of the concept
A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.
Very often the text is the same as a displayName of one of the codings.
The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.
C*E.9. But note many systems use C*E.2 for this
