I've seen this a few times, too, but I'm still a little bit of a  
Newbie.  I've run into times where simply renaming a rule fixes an  
issue.  I ran into this last week, but I don't remember what the  
actual issue wound up being.  Anyway, my hunch is that you might need  
to rename "type."  Maybe it conflicts with something else in the  
namespace.
