-  Here's our wire format:
-
-  Stream = TaggedData*
-
-  TaggedData = Tag Length Data
-       where the integer value of 'Length' is the length of 'data'.
-
-  Tag = HByte* LByte
-       where HByte is a byte with the high bit set, and LByte is a byte
-       with the high bit clear. The integer value of the tag is taken
-       by concatenating the lower 7 bits from all the tags.  So for example,
-       the tag 0x66 is encoded as [66], whereas the tag 0x166 is encoded as
-       [82 66]
-
-  Length = Integer
-
-  Integer = NNibbles Nibble* Padding?
-       where NNibbles is a 4-bit value encoding the number of nibbles-1,
-       and each Nibble is 4 bits worth of encoded integer, in big-endian
-       order.  If the total encoded integer size is an odd number of nibbles,
-       a final padding nibble with value 0 is appended.
