Used By: This entry is used directly by one other data structure in this standard, a MSG called
MSG_RoadSideAlert <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
8.3 Data Element: DE_FurtherInfoID [ATIS]
Use: This data element provides a link number to other messages (described here and in other message set
standards) which relate to the same event. Use zero when unkown or not present.
ASN.1 Representation:
FurtherInfoID ::= INTEGER (0..65535)
-- a link to any other incident
-- information data that may be available
-- in the normal ATIS incident description
-- or other messages
-- two bytes in length
XML Representation:
<xs:simpleType name="FurtherInfoID" >
<xs:annotation>
<xs:documentation>

Used By: This entry is used directly by one other data structure in this standard, a MSG called
MSG_RoadSideAlert <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
Remarks: Some message sets allow a request of other relevant messages by use of this ID, some others do
not. Some messages do not yet support this ID and force the message receiver to sort the recovered
message to align event geographically. This is expected to be an area of harmonization. Developers should
also note that data from different source agencies can vary with the numbering used as well.
8.4 Data Element: DE_HorizontalDatum:cd [LRMS]
Use: The underlying horizontal geodetic datum for a geographic coordinate.
ASN.1 Representation:
HorizontalDatum ::= ENUMERATED {wgs-84 (0),
wgs-84egm-96 (1),
nad83 (2),
nad27 (3),
... -- # LOCAL_CONTENT
