Notes: this is really a rule about specifications, implying that another specification (which might be application documentation) either makes this element <code>populate</code>, or explains how the use cases that involve this element do not arise, or how they are handled. An example: IPA marks Patient.active must-handle and must-explain. Client applications must process Patient.active correctly if they see it, but many (though <em>not all</em>) specifications and/or applications ensure that Patient.active will never be false, and so it will never be populated e.g. MedMij in Netherlands prohibits use of Patient.active, and explains that it is never false.</p>

Notes: Applications are still able to inform the user that a value cannot be processed correctly and may ignore the data, but applications aren't able to reject an instance merely because the element is present (which would be allowed for elements that do not have this obligation). A system MAY raise an error if the value provided is not valid or violates specific business rules.

This applies to non-valid constraints, not to non-valid syntax or failure to meet base resource validity expectations.

Notes: this rule is vague in that doesn't specify any particular handling of the element. But it's important because an application that ignores this element is non-conformant. A good example would be a status code of 'entered-in-error' - how exactly a Resource Consumer handles this depends on the use case etc., but the application can never simply ignore such a status code. Note that whether the resource or information from it is stored for later use is irrelevant - when the resource or information in it is processed, the consequences of the element are considered. That may mean not retaining the information for later use, or informing the user, etc. Typically, this obligation marks that there are known patient safety issues that can arise if the element is ignored. Implementers should pay particular attention to the possible range of values for the element from a safety perspective.</p>

Notes: exactly how it is displayed is not specified, but it means that a human looking at the content of the resource is made aware of the value of the element so that they can consider the meaning of the resource</p>

<description
value="Codes that describe application obligations for handling FHIR content. There are five kinds of codes in this code system:
* Categorizer codes: ResourceProducerObligations, ResourcesExchangerObligations, and ResourceConsumerObligations which are used to construct value sets and indicate the contexts in which the obligations apply. Note that many applications will be producers, consumers, and potentially exchangers simultaneously, so there is no need to limit obligations to only one category. These are abstract and cannot be declared as obligations.
* Qualifier codes: SHALL/SHOULD/MAY which convey the 'strength' of an obligation. These are also abstract and cannot be declared as obligations.
* Generic codes - these describe abstract functional obligation behaviors applications may implement, but do not specify a specific strength. They may be organized in a hierarchy where one generic code specializes another. These are also abstract cannot be declared as obligations.
* Leaf obligation codes - these are specific qualified obligations that can be declared by a data element and represent leaf-level obligations. They always inherit from a qualification concept and usually inherit from a functional code concept. These codes *can* be declared as obligations.
* Composite codes - these specialise Leaf obligation codes, inheriting the expectations of multiple concrete obligations. They represent common or externally defined combinations of obligations for ease of reference. These codes can also be declared as obligations."/>
