[PRD] Refraction Semantics may be WRONG!

I've discovered that refraction in OBR and Jess do not conform to the 
PRD spec. In particular, the
http://www.w3.org/2005/rules/wiki/Modify_noloop test case will always 
loop. The issue is that the PRD spec includes only the Forall variables 
in the rule instance, but my system(s) also includes the Exists 
variables in the rule instance.

What do the other PR systems do? Can you please try the Modify_noloop test?
