DF_Approach <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
6.46 Data Frame: DF_SpeedandHeadingConfidence
Use: A single byte long data frame combining multiple related bit fields into one byte.
ASN.1 Representation:
SpeedandHeadingConfidence ::= SEQUENCE {
heading HeadingConfidence, -- 3 bits
speed SpeedConfidence, -- 3 bits
throttle ThrottleConfidence -- 2 bits
}

6.47 Data Frame: DF_Tail
Use: This data structure is a way to add pairs of names and associated values to a message. It typically
appears at the end of a message (hence the name "tail"). The value carried in this portion of the message
