                 need to validate that a correct code was used at some point in the past. A typical
                 example of this would be where code selection is constrained to the set of codes
                 that were available when the patient was treated, not when the record is being
                 edited. Note that which date is appropriate is a matter for implementation policy.</p>

                 stating that the validation is being performed in a context where a concept designated
                 as 'abstract' is appropriate/allowed to be used, and the server should regard abstract
                 codes as valid. If this parameter is false, abstract codes are not considered to
                 be valid.</p> 

              <p> Note that. 'abstract' is a property defined by many HL7 code systems that indicates
                 that the concept is a logical grouping concept that is not intended to be used
                 as a 'concrete' concept to in an actual patient/care/process record. This language
                 is borrowed from object-orientated theory where 'abstract' entities are never instantiated.
                 However in the general record and terminology eco-system, there are many contexts
                 where it is appropriate to use these codes e.g. as decision making criterion, or
                 when editing value sets themselves. This parameter allows a client to indicate
                 to the server that it is working in such a context.</p>
