- * perform any postprocessing necessary (like hashing (some of) the data
- * to create a digest that gets included at the end) as well as shoving
- * the data off wherever it needs to go.  (In order to "tune" any processing,
- * you can set a "notify proc" as described above in the decoding case.)
- *
- * The parameters:
- * - "arg" is an opaque pointer that you provided at the same time you
- *   specified a function of this type
- * - "data" is a buffer of length "len", containing the encoded bytes
- * - "depth" is how deep in a nested encoding we are (it is not usually
- *   valuable, but can be useful sometimes so I included it)

- *   octets for identifier, length, contents, or end-of-contents
