Remarks: [Note:] Can this be combined with the "event flag" to be is in intersectionViolation work to
make one item?
Try to combine these two in next revision.
7.145 Data Element: DE_TwoByteTagList REMOVE
Use: A set of values (two bytes long) which assigns the tag value for data elements or data frames NOT
defined in the standard which could be transmitted in the WSM encoding format of encoded bytes. The
definition of these elements (semantic meaning and transmitted byte length) is expected to be exchanged by
the using parties by means outside the scope of this standard. The value range where the most significant
byte is set to zero is reserved for use in mapping to existing single byte tags into this range (where the
lower byte shall follow in the setting and meaning provided by the StdTagList element). The value range
where the most significant byte is set to 255 shall be reserved for future use. In keeping with the general
practices for ITS for expansion ranges, local values should begin to assign with an upper value of 127. So
in practice the first assigned element would be 0x80, 0x01 and so on. The sub-range with an upper byte
of 0x32 to 0x64 is further defined to be data of variable length where the byte following the two
byte tag is the byte count of the data to follow.
ASN.1 Representation:
TwoByteTagList ::= INTEGER (0..65535)
-- Values with the upper byte = 0 TO 127, or = 255
-- are reserved for use by the DSRC std
-- Local use should set the upper byte to 127 and above
