Are you talking about the cryptography description? Not sure what you are referring to with the "<commas>", but these are cryptographic notations. The "+" indicates concatenation.

12. A sends B: RSA(pubkey_B,EsKeyA + randB)

For example this notation means that A sends to B a message that is the RSA of a data field that A calculates using B's public key. The data field consists of the session key EsKeyA concatenated with a random number that B sent previously, randB.

Or something like that...
