Three DDL1 attributes are used to provide text descriptions of a defined data item. These are present in a dictionary for human readability, browser software or for the production of text dictionaries such as those in Part 4. This group of attributes is not machine interpretable. The _definition attribute provides a text description and as such is the primary semantic content in a defined data item. It may also be used to provide supplementary information about other machine-parsable attributes in the definition (see the definition in Fig. 2.5.5.3). The attributes _example and _example_detail are used to show typical instantiations of the defined item, as also shown in Fig. 2.5.5.6.
