The burden is entirely on the application to decide what gets selected
and when it gets updated.  Yes, the app has to send a message to the
server with the selection.  The clipboard process is more complicated in
X than it is in Windows.

If you want to read about it, chapter 10.3 of volume I of the old
O'Reilly books on Xlib describe the process.   You can read about
XSetSelectionOwner and XConvertSelection, and the SelectionNotify event.
