 Specifies a preferred order in which to use a set of contacts. ContactPoints with lower rank values are more preferred than those with higher rank values.

 Note that rank does not necessarily follow the order in which the contacts are represented in the instance.

Ranks need not be unique.  E.g. it's possible to have multiple contacts with rank=1.  If the ranks have different systems or uses, this would be interpreted to mean "X is my most preferred phone number, Y is my most preferred email address" or "X is my preferred home email and Y is my preferred work email".  If the system and use for equally-ranked contacts are the same, then the level of preference is equivalent for both repetitions.

Ranks need not be sequential and not all repetitions must have a rank.  For example, it's possible to have 4 contacts with ranks of 2, 5 and two with no rank specified.  That would be interpreted to mean the first is preferred over the second and no preference stated for the remaining contacts. */

It is possible to specify a rate over time (for example, 100 ml/hour) using either the rateRatio and rateQuantity.  The rateQuantity approach requires systems to have the capability to parse UCUM grammar where ml/hour is included rather than a specific ratio where the time is specified as the denominator.  Where a rate such as 500ml over 2 hours is specified, the use of rateRatio may be more semantically correct than specifying using a rateQuantity of 250 mg/hour. */

When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly.

When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array.

When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e.,

1. If primitive: it must match exactly the pattern value
2. If a complex object: it must match (recursively) the pattern value
3. If an array: it must match (recursively) the pattern value

If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions.  If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See [Examples of Patterns](elementdefinition-examples.html#pattern-examples) for examples of pattern usage and the effect it will have.

 If true, implementations that produce or consume resources SHALL provide "support" for the element in some meaningful way.

If false, whether to populate or use the data element in any way is at the discretion of the implementation.

 "Something meaningful" is context dependent and impossible to describe in the base FHIR specification. For this reason, the mustSupport flag is never set to true by the FHIR specification itself - it is only set to true in profiles.  A profile on a type can always make mustSupport = true if it is false in the base type but cannot make mustSupport = false if it is true in the base type.   This is done in [Resource Profiles](profiling.html#mustsupport), where the profile labels an element as mustSupport=true. When a profile does this, it SHALL also make clear exactly what kind of "support" is required, as this can mean many things.    Note that an element that has the property IsModifier is not necessarily a "key" element (e.g. one of the important elements to make use of the resource), nor is it automatically mustSupport - however both of these things are more likely to be true for IsModifier elements than for other elements. */

The effect of this is that the element cannot be ignored by systems: they SHALL either recognize the element and process it, and/or a pre-determination has been made that it is not relevant to their particular system. When used on the root element in an extension definition, this indicates whether or not the extension is a modifier extension.

 Only the definition of an element can set IsModifier true - either the specification itself or where an extension is originally defined. Once set, it cannot be changed in derived profiles (except in the special case of the defining a new extension).

    /** **Logical reference, when literal reference is not known**

 An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.

 When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy.

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference.  For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport).  One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).

This element only allows for a single identifier. In the case where additional identifers are required, use the [http://hl7.org/fhir/StructureDefinition/additionalIdentifier](http://hl7.org/fhir/extensions/StructureDefinition-additionalIdentifier.html) extension. */

 A timing schedule that specifies an event that may occur multiple times

 Specifies an event that may occur multiple times. Timing schedules are used to record when things are planned, expected or requested to occur. The most common usage is in dosage instructions for medications. They are also used when planning care of various kinds, and may be used for reporting the schedule to which past regular activities were carried out.

 Describes the occurrence of an event that may occur multiple times. Timing schedules are used for specifying when events are expected or requested to occur, and may also be used to represent the summary of a past or ongoing event.  For simplicity, the definitions of Timing components are expressed as 'future' events, but such components can also be used to describe historic or ongoing events.

A Timing schedule can be a list of events and/or criteria for when the event happens, which can be expressed in a structured form and/or as a code. When both event and a repeating specification are provided, the list of events should be understood as an interpretation of the information in the repeat structure. */

 **[TriggerDefinition](http://hl7.org/fhir/StructureDefinition/TriggerDefinition) v5.0.0**

 Defines an expected trigger for a module

 A description of a triggering event. Triggering events can be named events, data events, or periodic, as determined by the type element.

 If an event is a named-event, it means the event is completely pre-coordinated, and no other information can be specified for the event. If the event is one of the data- events, the data and condition elements specify the triggering criteria. The data element specifies the structured component, and the condition element provides additional optional refinement of that structured component. If the event is periodic, the timing element defines when the event is triggered. For both data- and periodic events, a name can be provided as a shorthand for the formal semantics provided by the other elements. */
