Hello,

I am new to that list, so please accept my apologies in advance for any
wrong doings with respect to the list etiquette !

I am currently reading draft-07 (Aug. 13, 2019) and something is not clear
to me with respect to the ClientInitKey format defined in section 7. The
array of ciphersuites cipher_suites is expected to have a length of 0 to
255 ciphersuites, while the array of public keys init_keys is expected to
have between one and 65535 public keys. At the same time, an above
paragraph says that the init_array MUST have the same length as the
cipher_suites array. Shouldn't both of them having a length <1,255> ? Or
what did I misunderstand?

Best,

Pascal
