+/**
+Defines the MTP array data type. MTP arrays consist of a contiguous sequence
+of objects of the same fixed length type, and are zero based. MTP does not 
+define variable length arrays, e.g. of string objects. Arrays are prepended 
+with a single 32-bit unsigned integer that identifies the number of elements 
+to follow. An empty array would consist of a single 32-bit integer containing
+the value 0x00000000. 
+
+MTP arrays are stored in a flat buffer to optimize streaming performance 
+to/from the MTP transport connection.
