  <description
               value="A profile on the Bundle transaction for ITI-65 Provide Document resources with UnContained allowed but requiring Comprehensive Metadata for MHD.

- [UnContained Comprehensive Metadata](StructureDefinition-IHE.MHD.UnContained.Comprehensive.ProvideBundle.html): `https://profiles.ihe.net/ITI/MHD/StructureDefinition/IHE.MHD.UnContained.Comprehensive.ProvideBundle` 
  - note that Minimal Metadata does not require containment, so UnContained Minimal is the same as Minimal Metadata
  - note that UnContained only applies to DocumentReference and SubmissionSet type Lists; so the following apply
  - shall be a Transaction Bundle
  - all resources shall be compliant with comprehensive unContained constraints, they may be marked comprehensive unContained
  - shall create a [SubmissionSet type List](StructureDefinition-IHE.MHD.Minimal.SubmissionSet.html) that is either minimal, comprehensive, or unContained
  - may create one or more [DocumentReference](StructureDefinition-IHE.MHD.Minimal.DocumentReference.html) that is either minimal, comprehensive, or unContained
    - with a document as a [Binary](http://hl7.org/fhir/R4/binary.html)
    - or, when implementing the **ITI-65 FHIR Document Publish** option, a [FHIR Document Bundle](http://hl7.org/fhir/R4/bundle.html)
  - may create/update one or more [Folder type List](StructureDefinition-IHE.MHD.Minimal.Folder.html) that is either minimal, comprehensive, or unContained
  - may create/update/read one [Patient](http://hl7.org/fhir/R4/patient.html)"/>

      <comment
               value="For many bundles, the timestamp is equal to .meta.lastUpdated, because they are not stored (e.g. search results). When a bundle is placed in a persistent store, .meta.lastUpdated will be usually be changed by the server. When the bundle is a message, a middleware agent altering the message (even if not stored) SHOULD update .meta.lastUpdated. .timestamp is used to track the original time of the Bundle, and SHOULD be populated.  

Usage:

* document : the date the document was created. Note: the composition may predate the document, or be associated with multiple documents. The date of the composition - the authoring time - may be earlier than the document assembly time
* message : the date that the content of the message was assembled. This date is not changed by middleware engines unless they add additional data that changes the meaning of the time of the message
* history : the date that the history was assembled. This time would be used as the _since time to ask for subsequent updates
* searchset : the time that the search set was assembled. Note that different pages MAY have different timestamps but need not. Having different timestamps does not imply that subsequent pages will represent or include changes made since the initial query
* transaction | transaction-response | batch | batch-response | collection : no particular assigned meaning

The timestamp value should be greater than the lastUpdated and other timestamps in the resources in the bundle, and it should be equal or earlier than the .meta.lastUpdated on the Bundle itself."/>

However, but if the fullUrl does look like a RESTful server URL (e.g. meets the [regex](http://hl7.org/fhir/R4/references.html#regex), then the 'id' portion of the fullUrl SHALL end with the Resource.id.

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."/>

However, but if the fullUrl does look like a RESTful server URL (e.g. meets the [regex](http://hl7.org/fhir/R4/references.html#regex), then the 'id' portion of the fullUrl SHALL end with the Resource.id.

Note that the fullUrl is not the same as the canonical URL - it's an absolute url for an endpoint serving the resource (these will happen to have the same value on the canonical server for the resource with the canonical URL)."/>

However, but if the fullUrl does look like a RESTful server URL (e.g. meets the [regex](http://hl7.org/fhir/R4/references.html#regex), then the 'id' portion of the fullUrl SHALL end with the Resource.id.

Note that the fullUrl is not the same as the canonical URL - it's an absolute url for an endpoint serving the resource (these will happen to have the same value on the canonical server for the resource with the canonical URL)."/>

However, but if the fullUrl does look like a RESTful server URL (e.g. meets the [regex](http://hl7.org/fhir/R4/references.html#regex), then the 'id' portion of the fullUrl SHALL end with the Resource.id.

Note that the fullUrl is not the same as the canonical URL - it's an absolute url for an endpoint serving the resource (these will happen to have the same value on the canonical server for the resource with the canonical URL)."/>

However, but if the fullUrl does look like a RESTful server URL (e.g. meets the [regex](http://hl7.org/fhir/R4/references.html#regex), then the 'id' portion of the fullUrl SHALL end with the Resource.id.

Note that the fullUrl is not the same as the canonical URL - it's an absolute url for an endpoint serving the resource (these will happen to have the same value on the canonical server for the resource with the canonical URL)."/>

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 can 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.
