 It is possible to write more complex winprop selection routines than
 those described in section \ref{sec:winprops}. To match a particular
 winprop using whatever way you want to, just set the \var{match}
-field of the winprop to a function that receives the client window
-as its sole parameter, and that returns \code{true} if the winprop
-matches, and \code{false} otherwise.

 If you want to match against (almost) arbitrary window properties,
 have a look at the documentation for the following functions, and
 their standard Xlib counterparts: \fnref{ioncore.x_intern_atom}
