	There doesn't seem to be and hard rules regarding this. If you create
an assembly and install it to the GAC then reference an assembly with a
different revision number the assembly will not load. So it seems to
only be done with System assemblies (from my research at least). I
haven't found any configuration files or anything that are doing the
remapping. Do you know how the runtime is supposed to know its ok to
disregard portions of version numbers?
