Table A.1: SIP input strings for the SIP/SDP dictionary
Appendix B. SDP input strings to the SIP/SDP static dictionary
For reference, this section lists the SDP input strings that were
used in generating the dictionary, as well as a priority value, the
offset of the string in the generated dictionary, the length of the
string, and one or more references into the referenced documents that
motivate the presence of this string. Note that the notation
"[CRLF]" stands for a sequence of two bytes with the values 0x0d and
0x0a, respectively.
The priority value is used for determining the position of the string
in the dictionary. Lower priority values (higher priorities) cause
the string to occur at a later position in the dictionary, making it
more efficient to reference the string in certain compression
algorithms. Hence, lower priority values were assigned to strings
more likely to occur.
