In this thread you say you're a 'manager of X.org'. You also make a strange claim about Wayland that doesn't appear to have any substance.
Then, in this thread, you ask either a very basic question or you ask a very complex question in a very simple manner. If someone is managing a large project like X.org, I'd expect them to ask better questions or already have this information.
Additionally, I can find no references to your name being associated with X.org.
