Section 7 says:
The Diffie-Hellman public value is obtained by concatenating the x and y values. The format of the Diffie-Hellman shared secret value is the same as that of the Diffie-Hellman public value.
Notes:
The last paragraph is incorrect. The Diffie-Hellman shared secret
contains only the x value. The y value is not included in the shared
secret.
