46 * @brief Roughly verify the message is correctly formed
47 * 1) all mandatory tags are present
48 * 2) all elements have expected data type
49 * 3) any tag can only appear once
50 * 4) At the top level of the structure, unknown tags are ignored for forward compatibility
51 * @note The main use of this function is to print out what we're
52 * receiving during protocol development and debugging.
53 * The encoding rule has changed in IM encoding spec so this
54 * check is only "roughly" conformant now.
