+ 4 byte integer in big endian format that determines the number of
+ key-value pairs in the map. Key and value pairs (<c>Ki => Vi</c>)
+ are encoded in the <c>Pairs</c> section in the following order:
+ <c>K1, V1, K2, V2,..., Kn, Vn</c>.
+ Duplicate keys are <em>not allowed</em> within the same map.
