ValueSet
Expansion performed internally based on codesystem Operation Synchronicity Control v6.0.0-ballot3 (CodeSystem)
This value set contains 3 concepts
| System | Code | Display | Definition |
http://hl7.org/fhir/synchronicity-control |
synchronous | Synchronous | This operation is invoked synchronously |
http://hl7.org/fhir/synchronicity-control |
asynchronous | Asynchronous | This operation is invoked asynchronously. |
http://hl7.org/fhir/synchronicity-control |
either | System | This operation can be invoked either synchronously or asynchronously. |

Explanation of the columns that may appear on this page:
| Lvl | A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information |
| Source | The source of the definition of the code (when the value set draws in codes defined elsewhere) |
| Code | The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract') |
| Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application |
| Definition | An explanation of the meaning of the concept |
| Comments | Additional notes about how to use the code |
