com.apple.developer.browser.app-installation
An entitlement that enables a browser to install alternative distribution apps from a website.
Discussion
The system requires that your browser app have this entitlement to install alternative marketplace apps from a webpage using MarketplaceKit. Browser apps that render with either WebKit or BrowserEngineKit need the entitlement. Apple enables it on your account along with the default browser entitlement (com.apple.developer.web-browser).
Your browser app needs to enforce specific webpage criteria as part of using this entitlement. For more information, see Enabling alternative distribution app installation in a browser.
If your account receives this entitlement, provision your app with the entitlement according to: Provisioning with managed capabilities.
