Structuresshall be encoded as JSON objects.

If the value of a field is NULL it shall be omitted from the encoding.

For example, instances of the structures:

struct Type2

{

Int32 A;

Int32 B;

Char* C;

};

struct Type1

{

Int32 X;

Int32 NoOfY;

Type2* Y;

Int32 Z;

};

Are represented in JSON as:

{

"X":1234,

"Y":[ { "A":1, "B":2, "C":"Hello" }, { "A":3, "B":4 } ],

"Z":5678

}

Where “C” is omitted from the second Type2 instance because it has a NULL value.
