The "Alternate Selection X-Server" is
a concept in which a PDM from anoth-
er Print X-Server can be borrowed by a
client. Maybe the alternate PDM has
features not found on the clients nor-
mal Print X-Server PDM.
PDM_START property: PDM to client {
start_code
atom value
}
Note: All "selection" communication is done
through the Selection X-Server, but the final
OK/Cancel ClientMessage still goes through
the Print X-Server, hebce the extra arrow.
