[RFC] DOM Living Standard API

Hi Internals, Thomas and I are working on updating the ext/dom to add support for the current DOM Living Standard API as standardized here: https://dom.spec.whatwg.org/ https://wiki.php.net/rfc/dom_living_standard_api This RFC is targeting 7.4 and contains three independent changes: - a set of new methods and interfaces that can be implemented BC as addition to the existing ext/dom. - a removal of a few "dead" classes that are exposed to userland, but neither documented nor containing implementation code. - a compatibility layer to switch the implementation between DOM Level 1-3 and the Living Standard in places where BC is not possible. A pull request includes a nearly complete implementation of the new methods, but nothing of the cleanup/compatibility yet: https://github.com/beberlei/php-src/pull/1 We are looking forward for your feedback. greetings Benjamin
