This is a draft document of the SAE ATIS committee, subject to change.
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_ITIS_EventType <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
6.5 Data Element: DE_Delays, Status, And Cancellations
Use: The ITIS enumeration list commonly referred to as "Delays, Status, And Cancellations," is assigned
the upper byte value of [06] (which provides for value ranges from 1536 to 1791, inclusive). This list is
formally called "DelayStatusCancellation" 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 36 different
phrases, divided into 5 further sub-categories (the division into these sub-categories is informational only
and other groupings may also be used). The remaining 91 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 1664).
