Re: numbering

I see, perhaps we can combine the text I proposed with a variant on  
the bnf you mentioned;


and add to my proposal the additional text:

If a widget resource contains signatures that are not consistent in  
the number of digits in the names then the result of ordering will be  
implementation dependent.
