        <p> This operation returns a 200 Ok provided that it was possible to perform validation, irrespective
           of whether validation issues were found.  However, it is possible that certain errors
           in the validated content (e.g. invalid character set, broken JSON, etc.) may cause the
           overall validation operation to fail with a 4xx or 5xx series response.</p> 

        <p> Note: the correct behaviour of validation with regard to language (especially for Coding.display)

  <description value="The validate operation checks whether the attached content would be acceptable either
   generally, as a create, an update or as a delete to an existing resource.  The action
   the server takes depends on the mode parameter:  

* [mode not provided]: The server checks the content of the resource against any schema,
   constraint rules, and other general terminology rules 
* create: The server checks the content, and then checks that the content would be acceptable
   as a create (e.g. that the content would not violate any uniqueness constraints) 
* update: The server checks the content, and then checks that it would accept it as an
   update against the nominated specific resource (e.g. that there are no changes to immutable
   fields the server does not allow to change, and checking version integrity if appropriate)
   
* delete: The server ignores the content, and checks that the nominated resource is allowed
   to be deleted (e.g. checking referential integrity rules)  

Modes update and delete can only be used when the operation is invoked at the resource
   instance level.   The return from this operation is an [OperationOutcome](operationoutcome.html)

Note that this operation is not the only way to validate resources - see [Validating Resources](vali
  dation.html) for further information."/>
