Re: Time to work on a Rec track JS sandbox? was: CSP and innerHTML

An API that allows us to play with the DOM in a programmatic way (CSP is a
directive, for example, it would be nice if there was a way to be asked if
doing X is OK).

   - This seems similar to clearing the DOM and doing a bunch of
   document.register calls. Maybe we can have a way of saying
   document.open('text/html', null) to get a document without any registered
   DOM elements?
   - One could possibly achieve this with XML and document.register maybe?
