Definitions for the Extension-BookingDeadline extension.
See the documentation on how to interpret the contents of this table
| 0. Extension | |
| Definition | This field contains the date and time by which the appointment is instructed to take place at the latest. The field is used, for example, when it is necessary to express when the appointment is to take place, but the time has not yet been booked. Optional Extension Element - found in all resources. |
| Short | Date and time by which the appointment is instructed to be made at the latestOptional Extensions Element |
| Control | 0..1* 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.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. |

| Summary | false |
| Fixed Value | |
| 4. Extension.value[x] | |
| Definition | This field contains the date and time by which the appointment is instructed to take place at the latest. The field is used, for example, when it is necessary to express when the appointment is to take place, but the time has not yet been booked. If the appointment is instructed to take place by a certain date, the last time of the day is used in the appointment booking. For example, if the appointment must take place by 15th of March 2025 at the latest, the time is presented as 2025-03-15T23:59:59+00:00. Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). |

| 2. Extension.id | |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | Unique id for inter-element referencing |

| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. Extension.extension | |
| Definition | 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 | Additional 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. |
