              <p> In some cases (e.g. when creating examples for implementation guides or when checking
                 for potential interoperability issues with a new communication partner), it can
                 be useful to know when data elements are present in an instance when those elements
                 are not 
                <code> mustSupport</code>  in the profile(s) the instance is being validated against. Identifying situations
                 where this occurs might drive a change to the profile or cause a designer to drop
                 an element from the instance. In other cases, the presence of the element can be
                 fine and the information message ignored.

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