This element defines the attributes for a specific segment.
Base definition for all types defined in FHIR type system.
This is the three letter code for the segment.
This is a short display name for human reading.
This a short description of this segment.
This boolean value indicates whether this segment is still active and can be used. The default value is false.
Which WG is the steward for this segment.
This boolean value indicates whether the last element according to the field definition may repeat. The default value is false.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
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 managable, 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.
Must have either extensions or value[x], not both
Extensions that cannot be ignored even if unrecognized
May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, 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. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Modifier extensions allow for extensions that *cannot* be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the [definition of modifier extensions](http://hl7.org/fhir/R5/extensibility.html#modifierExtension).
Modifier extensions are expected to modify the meaning or interpretation of the element that contains them
This value indicates wheether this field has to be implemented. The default value is empty, i.e. optional.
This element specifies the concept domain to which this data element is bound.
Which value set is bound to this field. Overwrites the binding as provided by the data element definition.
