This is a demonstration plugin for developers who need to customize what data gets included in a site export. It shows how to use specific hooks to add information from other plugins into the export file, acting as a reference implementation rather than a tool for direct end-user functionality.

Hook Implementation Example: Provides clear, working code that shows exactly how to intercept and modify the export process to include additional data. Class-Based Structure: The plugin is written using a proper class and WP_XMLWriter, demonstrating a modern and maintainable coding approach. Practical Reference: Serves as an immediate, executable guide for developers looking to understand the export extension API without reading abstract documentation. Minimal Overhead: The plugin itself does not perform any actions unless the core export plugin is active, ensuring it doesn't affect site performance when used only for study. Direct Code Inspection: Developers can examine the source to see how filters and actions are applied, making the export extension mechanics transparent and learnable.
