Elements defined in Ancestors:
The logical id of the resource, as used in the URL for the resource. Once assigned, this
value never changes.,
The metadata about the resource. This is content that is maintained by the infrastructure.
Changes to the content might not always be associated with version changes to the resource.,
A reference to a set of rules that were followed when the resource was constructed, and
which must be understood when processing the content. Often, this is a reference to an
implementation guide that defines the special rules along with other profiles etc.,
,
A human-readable narrative that contains a summary of the resource and can be used to
represent the content of the resource to a human. The narrative need not encode all the
structured data, but is required to contain sufficient detail to make it "clinically
safe" for a human to just read the narrative. Resource definitions may define what
content should be represented in the narrative to ensure clinical safety.,
These resources do not have an independent existence apart from the resource that contains
them - they cannot be identified independently, and nor can they have their own independent
transaction scope.,
May be used to represent additional information that is not part of the basic definition
of the resource. 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.,
May be used to represent additional information that is not part of the basic definition
of the resource and that modifies the understanding of the element that contains it and/or
the understanding of the containing element's descendants. Usually modifier elements provide
negation or qualification. 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 is allowed to define an extension, there is a set of requirements that SHALL
be met as part of the definition of the extension. Applications processing a resource
are required to check for modifier extensions.
Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource
(including cannot change the meaning of modifierExtension itself).

When a resource has no narrative, only systems that fully understand the data can display
the resource to a human safely. Including a human readable representation in the resource
makes for a much more robust eco-system and cheaper handling of resources by intermediary
systems. Some ecosystems restrict distribution of resources to only those systems that
do fully understand the resources, and as a consequence implementers may believe that
the narrative is superfluous. However experience shows that such eco-systems often open
up to new participants over time.
Name should be usable as an identifier for the module by machine processing applications
such as code generation
not(exists(for $type in distinct-values(f:uniqueId/f:type/@value) return if (count(f:uniqueId[f:type
/@value=$type and f:preferred/@value=true()])>1) then $type else ()))
The logical id of the resource, as used in the URL for the resource. Once assigned, this
value never changes.
The only time that a resource does not have an id is when it is being submitted to the
server using a create operation.
The metadata about the resource. This is content that is maintained by the infrastructure.
Changes to the content might not always be associated with version changes to the resource.
A reference to a set of rules that were followed when the resource was constructed, and
which must be understood when processing the content. Often, this is a reference to an
implementation guide that defines the special rules along with other profiles etc.
Asserting this rule set restricts the content to be only understood by a limited set of
trading partners. This inherently limits the usefulness of the data in the long term.
However, the existing health eco-system is highly fractured, and not yet ready to define,
collect, and exchange data in a generally computable sense. Wherever possible, implementers
and/or specification writers should avoid using this element. Often, when used, the URL
is a reference to an implementation guide that defines these special rules as part of
it's narrative along with other profiles, value sets, etc.
This element is labeled as a modifier because the implicit rules may provide additional
knowledge about the resource that modifies it's meaning or interpretation
Language is provided to support indexing and accessibility (typically, services such as
text to speech use the language tag). The html language tag in the narrative applies
to the narrative. The language tag on the resource may be used to specify the language
of other presentations generated from the data in the resource. Not all the content has
to be in the base language. The Resource.language should not be assumed to apply to the
narrative automatically. If a language is specified, it should it also be specified on
the div element in the html (see rules in HTML5 for information about the relationship
between xml:lang and the html lang attribute).
A human-readable narrative that contains a summary of the resource and can be used to
represent the content of the resource to a human. The narrative need not encode all the
structured data, but is required to contain sufficient detail to make it "clinically
safe" for a human to just read the narrative. Resource definitions may define what
content should be represented in the narrative to ensure clinical safety.
Contained resources do not have narrative. Resources that are not contained SHOULD have
a narrative. In some cases, a resource may only have text with little or no additional
discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary
for data from legacy systems where information is captured as a "text blob"
or where text is additionally entered raw or narrated and encoded information is added
later.
These resources do not have an independent existence apart from the resource that contains
them - they cannot be identified independently, and nor can they have their own independent
transaction scope.
This should never be done when the content can be identified properly, as once identification
is lost, it is extremely difficult (and context dependent) to restore it again. Contained
resources may have profiles and tags In their meta elements, but SHALL NOT have security
labels.
Containing new R4B resources within R4 resources may cause interoperability issues if
instances are shared with R4 systems

A natural language name identifying the naming system. This name should be usable as an
identifier for the module by machine processing applications such as code generation.
The name is not expected to be globally unique. The name should be a simple alphanumeric
type name to ensure that it is machine-processing friendly.The"symbolic name"
for an OID would be captured as an extension.
This is labeled as "Is Modifier" because applications should not use a retired
{{title}} without due consideration
The date (and optionally time) when the naming system was published. The date must change
when the business version changes and it must change if the status code changes. In addition,
it should change when the substantive content of the naming system changes.
Note that this is not the same as the resource last-modified-date, since the resource
may be a secondary representation of the naming system. Additional specific dates may
be added as extensions or be found by consulting Provenances associated with past versions
of the resource.
Usually an organization but may be an individual. The publisher (or steward) of the naming
system is the organization or individual primarily responsible for the maintenance and
upkeep of the naming system. This is not necessarily the same individual or organization
that developed and initially authored the content. The publisher is the primary point
of contact for questions or issues with the naming system. This item SHOULD be populated
unless the information is available from context.
Helps establish the "authority/credibility" of the naming system. May also
allow for contact.
The name of the organization that is responsible for issuing identifiers or codes for
this namespace and ensuring their non-collision.
This is the primary organization. Responsibility for some aspects of a namespace may
be delegated.
This will most commonly be used for identifier namespaces, but categories could potentially
be useful for code systems and authorities as well.
A coded type for an identifier that can be used to determine which identifier to use for
a specific purpose.
A free text natural language description of the naming system from a consumer's perspective.
Details about what the namespace identifies including scope, granularity, version labeling,
etc.
This description can be used to capture details such as why the naming system was built,
comments about misuse, instructions for clinical use and interpretation, literature references,
examples from the paper world, etc. It is not a rendering of the naming system as conveyed
in the 'text' field of the resource itself. This item SHOULD be populated unless the information
is available from context (e.g. the language of the naming system is presumed to be the
predominant language in the place the naming system was created).
The content was developed with a focus and intent of supporting the contexts that are
listed. These contexts may be general categories (gender, age, ...) or may be references
to specific programs (insurance plans, studies, ...) and may be used to assist with indexing
and searching for appropriate naming system instances.
When multiple useContexts are specified, there is no expectation that all or any of the
contexts apply.
It may be possible for the naming system to be used in jurisdictions other than those
for which it was originally designed or intended.
Provides guidance on the use of the namespace, including the handling of formatting characters,
use of upper vs. lower case, etc.
Multiple identifiers may exist, either due to duplicate registration, regional rules,
needs of different communication technologies, etc.
Unique id for the element within a resource (for internal references). This may be any
string value that does not contain spaces.
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

Different identifier types may be used in different types of communications (OIDs for
v3, URIs for FHIR, etc.). Other includes RUIDs from v3, standard v2 code name strings,
etc.
The string that should be sent over the wire to identify the code system or identifier
system.
If the value is a URI intended for use as FHIR system identifier, the URI should not contain
"\" or "?" or "," since this makes escaping very difficult.
If there are multiple ids, and one is labeled "preferred", then the assumption
is that the others are not preferred. In the absence of any id marked as preferred, no
inference can be drawn
e.g. "must be used in Germany" or "was initially published in error with
this value".
Identifies the period of time over which this identifier is considered appropriate to
refer to the naming system. Outside of this window, the identifier might be non-deterministic.
Within a registry, a given identifier should only be "active" for a single namespace
at a time. (Ideally, an identifier should only ever be associated with a single namespace
across all time).
A curated namespace that issues unique symbols within that namespace for the identification

Helps establish the "authority/credibility" of the naming system. May also
allow for contact.
The name of the organization that is responsible for issuing identifiers or codes for
this namespace and ensuring their non-collision.
This is the primary organization. Responsibility for some aspects of a namespace may
be delegated.
This will most commonly be used for identifier namespaces, but categories could potentially
be useful for code systems and authorities as well.
A coded type for an identifier that can be used to determine which identifier to use for
a specific purpose.
A free text natural language description of the naming system from a consumer's perspective.
Details about what the namespace identifies including scope, granularity, version labeling,
etc.
This description can be used to capture details such as why the naming system was built,
comments about misuse, instructions for clinical use and interpretation, literature references,
examples from the paper world, etc. It is not a rendering of the naming system as conveyed
in the 'text' field of the resource itself. This item SHOULD be populated unless the information
is available from context (e.g. the language of the naming system is presumed to be the
predominant language in the place the naming system was created).
The content was developed with a focus and intent of supporting the contexts that are
listed. These contexts may be general categories (gender, age, ...) or may be references
to specific programs (insurance plans, studies, ...) and may be used to assist with indexing
and searching for appropriate naming system instances.
When multiple useContexts are specified, there is no expectation that all or any of the
contexts apply.
It may be possible for the naming system to be used in jurisdictions other than those
for which it was originally designed or intended.
Provides guidance on the use of the namespace, including the handling of formatting characters,
use of upper vs. lower case, etc.
Multiple identifiers may exist, either due to duplicate registration, regional rules,
needs of different communication technologies, etc.
Different identifier types may be used in different types of communications (OIDs for
v3, URIs for FHIR, etc.). Other includes RUIDs from v3, standard v2 code name strings,
etc.
The string that should be sent over the wire to identify the code system or identifier
system.
If the value is a URI intended for use as FHIR system identifier, the URI should not contain
"\" or "?" or "," since this makes escaping very difficult.
If there are multiple ids, and one is labeled "preferred", then the assumption
is that the others are not preferred. In the absence of any id marked as preferred, no
inference can be drawn
e.g. "must be used in Germany" or "was initially published in error with
this value".
Identifies the period of time over which this identifier is considered appropriate to
refer to the naming system. Outside of this window, the identifier might be non-deterministic.
Within a registry, a given identifier should only be "active" for a single namespace
at a time. (Ideally, an identifier should only ever be associated with a single namespace
across all time).
