     7> What I assume this to be is an encoding scheme for immutable directories that allows deriving deep-verify capability so that whole directory tree below can be verified recursively.
     8>
     9> This is done by encoding separately the readcaps of items contained in the directory (Plain_R) and verifycaps of the same items (Plain_V).
     10>
     11> By applying this scheme to the plaintexts together with convergence secret (CS) and encoding parameters you will get two encryption keys EncK_R and EncK_V for each part respectively.
