Use: The geographic longitude of a node, expressed in integer microdegrees, with reference to the
horizontal datum specified by horizontalDatum.

8.29 Data Frame: EXT_Tail [ATIS]
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
shall not be used to circumvent the structure of the messages. That said, this is an excellent way to add
further meta-data to a message or to add content which a local deployment feels is needed but which is not
currently in the message set.
ASN.1 Representation:
TailSet ::= SEQUENCE {
set SEQUENCE {
name IA5String(SIZE(1..32)),
value IA5String(SIZE(1..10000))
-- any internal structure of the value string is the
-- responsibility of the data creator to manage. If the
-- content is binary, convert to bin hex strings.
}
-- the order of the sets shall not be changed
