When CMIP services sends character strings, if the value contains the double quotation mark (") character, CMIP services encloses the value in single quotation marks. If the string does not contain the double quotation mark character, CMIP services encloses the value in 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, CMIP services sends the value to the application program in hexadecimal BER format, enclosed in delimiters. See Hexadecimal BER format for a description.
