Data elements represent a UTF
Data elements are signed 16 bit integers representing a real number with
5 bits for the integer component and 11 bits for the fractional component

Each value specifies signed offsets of the same type to be added to the
current parameter values
according to their valid range
Applying any offset other than zero to a boolean value will invert that value
The data field is 0 or more bytes as determined by the data type and number
