Type: defect
Priority: minor
Component: Libraries: Exceptions and conditions
Version: 5.91

In <14. Exceptions and conditions>, the only paragraph reads:

   Scheme allows programs to deal with exceptional situations using  
two cooperating facilities: The exception system allows the program,  
when it detects an exceptional situation, to pass control to an  
exception handler, and for dynamically establishing such exception  
handlers.  Exception handlers are always invoked with an object  
describing the exceptional situation.  Scheme's condition system  
provides a standardized taxonomy of such descriptive objects, as well  
as facility for defining new condition types.

But this makes it unclear what the two facilities are, exceptions and  
handlers or exceptions and conditions.  Rephrase.
