FWIW, while solving an X related STR last night,
I noticed 'xwininfo -id' takes hexidecimal ID numbers
on its command line, replete with the "0x" prefix and everything.
So I get the impression passing around ID's in hex might
be considered "normal behavior" for processes to tell each
other about other windows.
I imagine it's the one way guaranteed to uniquely identify
a window on an X server, since "window names" aren't necessarily
unique.

[e...@tahoe] $ xwininfo -name Untitled.fl <-- show a window's info
xwininfo: Window id: 0x3400002 "Untitled.fl" <-- hex ID printed by xwininfo
^^^^^^^^^
Absolute upper-left X: 1057
Absolute upper-left Y: 30
Relative upper-left X: 5
Relative upper-left Y: 24

[e...@tahoe] $ xwininfo -id 0x3400002 <-- use the hex ID instead of
name
^^^^^^^^^^^^^
xwininfo: Window id: 0x3400002 "Untitled.fl" <-- still works
Absolute upper-left X: 1057
Absolute upper-left Y: 30
Relative upper-left X: 5
Relative upper-left Y: 24
