Generated Narrative: CodeSystem issue-type

This case-sensitive code system http://hl7.org/fhir/issue-type defines the following codes in a Is-A hierarchy:

LvlCodeDisplayDefinition
1invalid Invalid ContentContent invalid against the specification or a profile.
2\u00a0\u00a0structure Structural IssueA structural issue in the content such as wrong namespace, unable to parse the content completely, invalid syntax, etc.
2\u00a0\u00a0required Required element missingA required element is missing.
2\u00a0\u00a0value Element value invalidAn element or header value is invalid.
2\u00a0\u00a0invariant Validation rule failedA content validation rule failed - e.g. a schematron rule.
1security Security ProblemAn authentication/authorization/permissions issue of some kind.
2\u00a0\u00a0login Login RequiredThe client needs to initiate an authentication process.
2\u00a0\u00a0unknown Unknown UserThe user or system was not able to be authenticated (either there is no process, or the proferred token is unacceptable).
2\u00a0\u00a0expired Session ExpiredUser session expired; a login may be required.
2\u00a0\u00a0forbidden ForbiddenThe user does not have the rights to perform this action.
2\u00a0\u00a0suppressed Information SuppressedSome information was not or might not have been returned due to business rules, consent or privacy rules, or access permission constraints. This information may be accessible through alternate processes.
1processing Processing FailureProcessing issues. These are expected to be final e.g. there is no point resubmitting the same content unchanged.
2\u00a0\u00a0not-supported Content not supportedThe interaction, operation, resource or profile is not supported.
2\u00a0\u00a0duplicate DuplicateAn attempt was made to create a duplicate record.
2\u00a0\u00a0multiple-matches Multiple MatchesMultiple matching records were found when the operation required only one match.
2\u00a0\u00a0not-found Not FoundThe reference provided was not found. In a pure RESTful environment, this would be an HTTP 404 error, but this code may be used where the content is not found further into the application architecture.
3\u00a0\u00a0\u00a0\u00a0deleted DeletedThe reference pointed to content (usually a resource) that has been deleted.
2\u00a0\u00a0too-long Content Too LongProvided content is too long (typically, this is a denial of service protection type of error).
2\u00a0\u00a0code-invalid Invalid CodeThe code or system could not be understood, or it was not valid in the context of a particular ValueSet.code.
2\u00a0\u00a0extension Unacceptable ExtensionAn extension was found that was not acceptable, could not be resolved, or a modifierExtension was not recognized.
2\u00a0\u00a0too-costly Operation Too CostlyThe operation was stopped to protect server resources; e.g. a request for a value set expansion on all of SNOMED CT.
2\u00a0\u00a0business-rule Business Rule ViolationThe content/operation failed to pass some business rule and so could not proceed.
2\u00a0\u00a0conflict Edit Version ConflictContent could not be accepted because of an edit conflict (i.e. version aware updates). (In a pure RESTful environment, this would be an HTTP 409 error, but this code may be used where the conflict is discovered further into the application architecture.).
2\u00a0\u00a0limited-filter Limited Filter ApplicationSome search filters might not have applied on all results. Data may have been included that does not meet all of the filters listed in the `self` `Bundle.link`.
1transient Transient IssueTransient processing issues. The system receiving the message may be able to resubmit the same content once an underlying issue is resolved.
2\u00a0\u00a0lock-error Lock ErrorA resource/record locking failure (usually in an underlying database).
2\u00a0\u00a0no-store No Store AvailableThe persistent store is unavailable; e.g. the database is down for maintenance or similar action, and the interaction or operation cannot be processed.
2\u00a0\u00a0exception ExceptionAn unexpected internal error has occurred.
2\u00a0\u00a0timeout TimeoutAn internal timeout has occurred.
2\u00a0\u00a0incomplete Incomplete ResultsNot all data sources typically accessed could be reached or responded in time, so the returned information might not be complete (applies to search interactions and some operations).
2\u00a0\u00a0throttled ThrottledThe system is not prepared to handle this request due to load management.
1informational Informational NoteA message unrelated to the processing success of the completed operation (examples of the latter include things like reminders of password expiry, system maintenance times, etc.).
1success Operation SuccessfulThe operation completed successfully.
