|Feature users and use cases=From the w3 change proposal:
"As a simple example, consider hosting a maps control in a page. The maps control is hosted from another domain and outside the hosting author’s control. Such a mash-up is a perfect use case for HTML5 Sandbox. However, many of these types of controls include links that are targeted to open in a new browsing context. There is an example of such a scenario at the IE Test Drive site (requires an HTML5 Sandbox supporting browser, such as IE10 Platform Preview 2, Chrome, or Safari)."
