# ExtraPropertyModel Documentation

## 1. Purpose

This module provides a model class `ExtraPropertyModel` for representing key-value pairs (ISO codes/user codes and their associated channel names) within the UI layer. It implements `IExtraProperty` and provides data binding support through `BasePropertyChanged`, along with a custom paste command infrastructure (`PasteCommandClass`) that handles clipboard text parsing and event publication for multi-field paste operations. This model serves as a bridge between raw property data and WPF UI components.
