[whatwg] Proposal: <intent> tag for Web Intents API

Understood.  The case still stands that we can use the <intent> tag in
the body, have script fallback if the publisher decides to add the
shim by way of adding the dom Element or just always including the
proxy code - or just have a nice piece of text/dom for some other
fallback mechanism of completing the action (such as a link to a
scriptlet).  We don't get this ability with the other methods
discussed (<meta> - <link>).

Note: I added a script element inside a video element and a supporting
browser still executed the code.  It is a shame because I think it is
a nice solution (in theory).
