I want code distributors to advertise which sandbox features I can safely restrict

[aarongustafson]

The sandbox attribute allows developers to restrict web features of embedded content, such as <iframe>. This is a hard-to-utilize security feature because code distributors do not provide sufficient documentation on the APIs used, likely leading to broken embeds. I want to be able to sandbox away with confidence!
