+    EGL Extension #not assigned
+
+Dependencies
+
+    Reguires EGL 1.4 or later.  This extension is written against the
+    wording of the EGL 1.4 specification.
+
+    EGL_KHR_base_image is required.
+
+Overview
+
+    This extension provides entry points for binding and unbinding the
+    wl_display of a Wayland compositor to an EGLDisplay.  Binding a
+    wl_display means that the EGL implementation should provide one or
+    more interfaces in the Wayland protocol to allow clients to create
+    wl_buffer objects.  On the server side, this extension also
+    provides a new target for eglCreateImageKHR, to create an EGLImage
+    from a wl_buffer
+
+    Adding a implementation specific wayland interface, allows the
+    EGL implementation to define specific wayland requests and events,
+    needed for buffer sharing in a EGL wayland platform.
+
+IP Status
+
+    Open-source; freely implementable.
+
+New Procedures and Functions
+
+    EGLBoolean eglBindWaylandDisplayWL(EGLDisplay dpy,
+                                       struct wl_display *display);
+
+    EGLBoolean eglUnbindWaylandDisplayWL(EGLDisplay dpy,
+                                         struct wl_display *display);
+
+New Tokens
+
+    Accepted as <target> in eglCreateImageKHR
+
+        EGL_WAYLAND_BUFFER_WL                   0x31D5
+
+Additions to the EGL 1.4 Specification:
+
+    To bind a server side wl_display to an EGLDisplay, call
+
+        EGLBoolean eglBindWaylandDisplayWL(EGLDisplay dpy,
+                                           struct wl_display *display);
+
+    To unbind a server side wl_display from an EGLDisplay, call
+    
+        EGLBoolean eglUnbindWaylandDisplayWL(EGLDisplay dpy,
+                                             struct wl_display *display);
+
+    eglBindWaylandDisplayWL returns EGL_FALSE when there is already a
+    wl_display bound to EGLDisplay otherwise EGL_TRUE.
+
+    eglUnbindWaylandDisplayWL returns EGL_FALSE when there is no
+    wl_display bound to the EGLDisplay currently otherwise EGL_TRUE.
+
+    Import a wl_buffer by calling eglCreateImageKHR with
+    wl_buffer as EGLClientBuffer, EGL_WAYLAND_BUFFER_WL as the target,
+    and an empty attribute_list.
