Default values for Array and Struct

## Background
When a non-null default (fallback) value for complex types (array, struct) would be requested during the **Standardization** it will stop the process with exception because the value is not defined.

## Feature
And default (fallback) value for Array and Struct types

## Proposed Solution
**Array**: empty array
**Struct**: each field is flled with default value of the field's type
