6. Data Element Definitions
Messages and data frames specified in Clause 7 and in other standards that use ITIS phrases are composed
of message elements. In some cases, these message elements shall be DFs (found in the here or in the other
standards). In other cases, these message elements shall be DEs. Any message or data frame specified in
Clause 7 shall have all of its DEs and DFs specified in this clause, except those DEs that are primitive
ASN.1 data types or those that are adopted from other functional areas, or defined in other volumes of the
family of standards. In the later cases, the referenced standards shall be consulted.
The productions of ASN.1 which follows shall be considered normative in nature. While the majority of
the normative content is reflected in the actual syntax of the ASN.1 some entries also have additional
statements in the ASN.1 comments which shall be considered to be normative as well. In addition, the
commentary provided with each entry may also provide additional normative restrictions on the proper use
of the entry which shall be followed. The XML productions follow directly from the ASN.1 specifications
and the same rules shall be applied.
6.1 Data Element: DE_Accidents and Incidents
Use: The ITIS enumeration list commonly referred to as "Accidents and Incidents," is assigned the upper
byte value of [02] (which provides for value ranges from 512 to 767, inclusive). This list is formally called
"AccidentsAndIncidents" in the ASN.1 and XML productions. Items from this enumeration list can be
used as an event category classification. This list contains a total of 52 different phrases, divided into 6
further sub-categories (the division into these sub-categories is informational only and other groupings may
also be used). The remaining 75 values up to the lower byte value of [127] are reserved for additional
"national" phrases in this byte range. Local phrases may be added to the list starting with the lower byte
value of 128 and proceeding upward from there (in other words, the first value assigned for any local
additions to this list would be given the value 640).
