          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.

      Language is provided to support indexing and accessibility (typically, services such as

       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 &quot;clinically
       safe&quot; 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 &quot;text blob&quot;
       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.

      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.
      There can be no stigma associated with the use of extensions by any application, project,
       or standard - regardless of the institution or jurisdiction that uses or defines the extensions.
        The use of extensions is what allows the FHIR specification to retain a core level of
       simplicity for everyone.

       measure author and is not expected to be globally unique. For example, it might be a timestamp

       versions can be placed in a lexicographical sequence. To provide a version consistent
       with the Decision Support Service specification, use the format Major.Minor.Revision (e.g.
       1.0.0). For more information on versioning knowledge assets, refer to the Decision Support
       Service specification. Note that a version is required for non-experimental active artifacts.
      There may be different measure instances that have the same identifier but different versions.
