Could invokeTarget be used to provide a declarative option for some JavaScript APIs? I'm thinking specifcally of JavaScript APIs that require a user interaction (and so most demos involve the creation of a button element anyway) and that don't currently have an equivalent HTML element.

For example:

• The Fullscreen API already proposed.
• The Geolocation API
• The Web Share API moved to separate issue. [invokers] Share command #974

I'm not sure how the button invoketarget="geolocation" would work other than perhaps populating an input element using invoketarget.

Are there are other JavaScript APIs that match the same criteria?
