<xs:simpleType name="BSMblob-string">
<xs:restriction base="xs:base64Binary">
<xs:length value="50"/>
</xs:restriction>
</xs:simpleType >
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):
MSG
<XML>, and
MSG
In addition, this item may be used by data structures in other ITS standards.
Remarks: The byte order for packing shall follow the rules of ASN (MSB first). If a data element is not
to be transmitted (for example the Temporary ID value) then all bit of that value shall be set to zero. The
resulting data object is always exactly 37 bytes in length.
6.8 Data Frame: DF_BumperHeights
Use: The DF Bumper Heights data frame conveys the height of the font and rear bumper of the vehicle.
ASN.1 Representation:
BumperHeights ::= SEQUENCE {
frnt BumperHeightFront,
rear BumperHeightRear
}
XML Representation:
<xs:complexType name="BumperHeights" >
<xs:sequence>
<xs:element name="frnt" type="BumperHeightFront" />
<xs:element name="rear" type="BumperHeightRear" />
</xs:sequence>
</xs:complexType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleStatus <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
6.9 Data Frame: DF_Circle
Use: The Circle data frame used used to define a circle centered at a given point and extended to the given
raduis. It is typically used to describe the location of signs so that the receiving vehicle can determine if the
sign applies to them and their current path.
ASN.1 Representation:
Circle ::= SEQUENCE {
center Position3D,
raduis CHOICE {
raduisSteps INTEGER (0..32767),
-- in unsigned values where
-- the LSB is in units of 2.5 cm
miles INTEGER (1..2000),
km INTEGER (1..5000)
} --# UNTAGGED
}
XML Representation:
<xs:complexType name="Circle" >
<xs:sequence>
<xs:element name="center" type="Position3D" />
<xs:choice >
<xs:element name="raduisSteps" >
