Section Appendix A says:

mech-parameters    = ( algorithm / protocol /mode /
                             encrypt-algorithm / spi /
                             port1 / port2 )
encrypt-algorithm  = "ealg" EQUAL ( "des-ede3-cbc" / "null" )
spi                = "spi" EQUAL spivalue
port1              = "port1" EQUAL port
port2              = "port2" EQUAL port

It should say:

mech-parameters    = ( algorithm / protocol /mode /
                             encrypt-algorithm / spi-c / spi-s /
                             port-c / port-s )
encrypt-algorithm  = "ealg" EQUAL ( "des-ede3-cbc" / 
                             "aes-cbc" / "null" )
spi-c              = "spi-c" EQUAL spivalue
spi-s              = "spi-s" EQUAL spivalue
port-c             = "port-c" EQUAL port
port-s             = "port-s" EQUAL port


3GPP 33.203 has different ABNF than the Appendix in this RFC. Note the "spi-c", "spi-s", "port-c", "port-s" parameter names instead of "spi", "port1", or "port2". And a new algorithm token of "aes-cbc" as well.
The ABNF changes described here would have required substantial changes to the remainder of Appendix A. If the reporter wishes to make this update, he should submit an Internet-draft that updates this RFC.
