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 its narrative along with other profiles, value sets, etc."/>

Resource definitions may define what content should be represented in the narrative to ensure clinical safety. Contained resources do not have a narrative.

Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the summary. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.
