Used By: This entry is directly used by the following 2 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
MSG
In addition, this item may be used by data structures in other ITS standards.
8.6 Data Element: DE_ITIS_Text [ITIS]
Use: Simple text used with ITIS codes.
ASN.1 Representation:
ITIStext ::= IA5String (SIZE(1..500))
XML Representation:
<xs:simpleType name="ITIStext" >
<xs:restriction base="xs:string">
<xs:minLength value="1"/>
<xs:maxLength value="500"/>
</xs:restriction>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called DF_ITIS-
Codes_And_Text <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
8.7 Data Element: DE_MAYDAY_Heading_number [ATIS]
Use: The value of heading. This element is used to convey the heading of the device when moving. Units
are in 360/254 degrees where the value of 0x00 is taken to be due north, 0x01 is taken to be slightly east of
north.
ASN.1 Representation:
Heading ::= INTEGER (0..255)
-- Vaild Encoding rules , an unsigned 8 bit value
-- 0 = due north, larger going clockwise (east of north)
-- (0..253) 360/254 degrees per bit
-- 254 = no heading at all (stationary)
-- determined by
-- examining the velocity DE
-- 255 = heading not known
