XView is an X11 toolkit that is NOT based on the X Consortium standard Xt.

Like XView, Xt+ (as it used to be called) from Unix System Labs (of AT&T)
implements the OPEN LOOK specification; unlike XView, it uses libXt ( the
"intrinsics").  The intrinsics are a library of object-oriented support
tools for building widgets, but not themselves a widget set (the Athena
widgets, libXaw, are part of the MIT distribution of X11; these are NOT
part of the intrinsics, per se.)  Motif, from OSF, is a *different* set
of widgets (and a non OPEN LOOK look-and-feel) but is also based on the
intrinsics.

Having the various options and implementations seems to have done more
to confuse people than to help them by providing flexibility, but maybe
the confusions will be only temporary and the market will benefit from
having the options.  I think that was the original intent, anyway :-)
