	If you created a custom attribute struct and methods for
yourself, you would not have to have the show/store methods on the same
structure.  The structure, and the ##item_show/store macros, are a
convenience way to do it.
	It certainly could be done differently.  I cloned the sysfs
approach at the time.  Note that sysfs has a different methodology for
defining attributes now.
