This includes unformatted or formatted written language, multimedia data, or structured information in as defined by a different standard (e.g., XML-signatures.) Instead of the data itself, an may contain only a reference (see .) Note that the data type is a specialization of the data type when the media type is text/plain. |

Narrative
Note: links and images are rebased to the (stated) source
Data that is primarily intended for human interpretation or for further machine processing is outside the scope of HL7. This includes unformatted or formatted written language, multimedia data, or structured information as defined by a different standard (e.g., XML-signatures.) Instead of the data itself, an ED may contain only a reference (see TEL.) Note that the ST data type is a specialization of the ED data type when the ED media type is text/plain.
