+ <c>MAP_EXT</c> encodes a map. The <c>Arity</c> field is an unsigned
+ 4 byte integer in big endian format that determines the number of
+ key-value pairs in the map. All key terms follow in the <c>Keys</c>
+ section and then all value terms in the <c>Values</c> section. Keys
+ and values are paired according to order; first key with first value
+ and so on. Duplicate keys are <em>not allowed</em> within the same
+ map.
