[xwiki-devs] [proposal] Add an API function to drop permissions for the remainder of the document rendering.

Right now we have dropPermissions which makes a specific guarantee, there will not be any programming right for the duration of the request cycle. Sometimes a user might want to drop permissions for the duration of the document rendering. This would mean {{include}} macros, $doc.getRenderedContent() would allow permissions to be gained back while the included document was being rendered and after the content of that document is finished rendering, the permissions would be returned. I think it would do more harm than good to break the promise that dropPermissions() makes so I propose adding $doc.dropPermissions() to do this. I think $doc.dropPermissions() vs. $context.dropPermissions() is intuitive and easily explained but if anyone has another suggestion for a name, I'd be glad to hear it. WDYT? Caleb
