7.89 Data Element: DE_NMEA_MsgType
Use: The NMEA-MsgType provides the--- value defined in the NMEA standards for each message.
ASN.1 Representation:
NMEA-MsgType ::= INTEGER (0..32767)
XML Representation:
<xs:restriction base="xs:unsignedShort">
<xs:maxInclusive value="32767"/>
</xs:restriction>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a MSG called
MSG_NMEA_Corrections <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
7.90 Data Element: DE_NMEA_Payload
Use: The NMEA Payload element contains the stream so of bytes in the actual NMEA message that is
being sent.
ASN.1 Representation:
NMEA-Payload ::= OCTET STRING (SIZE(1..1023))

7.91 Data Element: DE_NTCIPVehicleclass,
Use: The DE_NTCIP Vehicle class data element is constructed of two 4-bit nibbles defined by the
guidelines of NTCIP 1211 (Object Definitions for Signal Control and Prioritization (SCP)) except that the
range is extended to be 0..15 for each.
NTCIP Clause 3.1.1.1.4 defines Priority Request Vehicle Class Type as follows: This object is the 'PRG
requested' class type (relative priority of a request). The order of precedence is by class type with 1 highest
and 10 (15 for this system) lowest. A request with a higher class type will override a lower class type.
NTCIP Clause 3.1.1.1.5 defines Priority Request Vehicle Class Level as follows: This object is the 'PRG
requested' class level (relative priority of a request within each class of request). The order of precedence
