Extension header names conform to the following structure:
SDOName = 1*VCHAR
HdrName = 1*VCHAR
; (RFC 5234 defines VCHAR as any visible character
; i.e. any character with ASCII value in the range
; 0x21 through 0x7E)
Header field code assignments, made by OMNA, are specified in the following table:
