Does "Other" include the character "-", and "Unicode Letter" 
presumably not include character "-"?  Does the "< xxx , yyy >"
notation mean the character sets xxx followed by yyy?
If these are true, then you're right.  It'd help if you
had included complete definitions for the <...>s.

I don't quite follow here.  Implementors of servers use this
draft/RFC to decide whether a newsgroup reference is "legal" or
not.  Don't think we could put your line above in the draft/RFC
to complete an infinite loop.....
