I do not agree with this assessment. The purpose behind the standards  
is to try to reduce the likelihood of harmful registrations and to  
maximize the benefit of IDN use. We plainly are drawing a line  
between the use of the standards for this purpose and the  
recommendation that other kinds of protection (restriction) be left  
to registries to implement.
