That's probably not a bad idea.  One slight change I would suggest is
having the attribute be specified by the IProcess interface and stored
on that facet of the application componentized.  See tickets #718 and
#761 in the tracker.  If someone contributes patches implementing some
functionality in this area I'll try to get it committed.
