Based on the discussion I wrote two patches: one for the wayland.xml (and wayland.dtd since the fact of the matter is that that file is still there), and one for scanner.c See 5dc0112f734d23d65a2bf9a78f11463d0294b6c7 and b6d5659c650056f66267f3f20fdbaf724138a61b in [0]. Is this a good format for sending patches? Or are actual patch emails preferred? The scanner.c code checks that the enum attribute of an <arg> is the name of an <enum> in the same <interface>. In that case, it checks that the type of the <arg> is an int or a uint, and if the <enum> had bitfield set to "true", that the type was indeed uint. If these properties are not satisfied, the scanner dies. Is that what was expected? Auke.
