| 0. code | |
| Definition | A string which has at least one character and no leading or trailing whitespace and where there is no whitespace other than single spaces in the contents |
| Short | Primitive Type code |
| Control | 0..* |
| Is Modifier | false |
| Summary | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 2. code.id | |
| Definition | unique id for the element within a resource (for internal references) Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | xml:id (or equivalent in JSON)Unique id for inter-element referencing |
| Control | 0..01 This element is affected by the following invariants: ele-1 |
| Type | string |
| Is Modifier | false |
| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. code.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 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. |
| 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. |
