Definitions for the consent-provision-limit extension.
Guidance on how to interpret the contents of this table can be foundhere
| 0. Extension | |
| Definition | Extension to express the limit on the permitted use of data. This extension should be used as a ModifierExtension as it is critical to the proper understanding of the consent. If the provision limit is not observed, then the consent is effectively not valid and should not be applied. Optional Extension Element - found in all resources. |

| 4. Extension.extension:control.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. |

| Comments | The FHIRPath expression is limited to the simple subset with the additional limitation that .resolve() that is not allowed. This is a more sophisticated mechanism of referring to an element than .element but does require the system resolving the item to be able to use at least FHIRPath. If the author of the limit has the ability to ensure an id will be present then .element might be more widely useable. |
