MDI on X11

[Matthias Ettrich <ettrich troll no>]

Hi again,

I'm currently implementing support for multiple document interfaces (MDI) in
both Qt and my new window manager. The protocol isn't yet finished, but the
issues involved are not that tricky as I at first expected them to be.

In other words: MDI _is_ possible on X11, without requiring the application to
emulate a window manager itself.

What's your opinion about that? Shall we add a common MDI protocol to the
specs?  I'd say yes, given that noone is forced to implement it.
