What do you think of this:

"The leaf instruction checks that the measurement is correct and
signature is signed with the key hashed to the four
+**IA32_SGXLEPUBKEYHASH{0, 1, 2, 3}** MSRs representing the SHA256 of a
public key."

I though that little more detail would make sense here (i.e. what do the
MSRs represent).
