Re: HYB - UMBATA

Hi Chad,
This is also a new term for me.  It is a term that evidently came 
about in some of the earlier iris talk discussions.  My first 
encounter with it was a message from Linda Mann.  Linda, maybe you can 
cue us as to its origin.  I think it is one of those tentative 
descriptions given to a pattern to help aid in making the discussion 
easier.
