What it does
This class provides destination type options for UPS shipping configuration in Magento's admin panel.
It extends the Generic source model to populate dropdown fields with available destination types (like residential or commercial addresses) that are used when configuring UPS shipping methods.
Developers use this when customizing UPS shipping options or creating admin configuration forms related to UPS delivery destinations.
