      1. Define an attribute of an object in *.idl file like below. 
         
cursors:
    description: "An array of cursor IDs to be killed."
    type: array<cursorId>
    cpp_name: cursorIds
    optional: false
      2. Pass an array-like object as a value of the field: 
        cursors:{
 '0': 10000,
 '1': 20000
}
      3. The object is successfully parsed.

      IDL generated parsers do not validate that the input element is a BSON array for attributes of type array<type>. The parsers do accept both - BSON arrays and objects with array layout (please see Steps To Reproduce for an example). Expected behavior is that only BSON arrays are accepted.
