CMIP services sends BIT STRINGs as strings of digits, without enclosing them in quotation marks. When CMIP services receives a null BIT STRING from an application program, CMIP services sends the null BIT STRING as two double quotation marks.

CMIP services places labels in the string for all elements of the syntax that are present.

If CMIP services cannot decode the value for a BIT STRING, including null BIT STRINGS, CMIP services sends the value to the application program in hexadecimal BER format, enclosed in delimiters. See Hexadecimal BER format for a description.
