I spent quite a long time looking at those protocols and their
client/compositor implementations (in Weston as well as in QTWayland). By
now I think I have at least a basic understanding of how they should
I was wondering where a high-level documentation describing how text
input is handled (with the help of an input method) should live. Since
those are unstable protocols, maybe adding an .md file somewhere in
wayland-protocols/unstable/ would be appropriate?
I have one question regarding the following request (I hope this is
the right place to ask):

I assume that the "window with word suggestions" that this request
enables the compositor to draw will be supplied by the input method
(though the current version of the input-method protocol does not seem
to provide an event/request for this yet). Is this assumption correct?
