There is a deeper issue here that I did not point out explicitly.

Alan said: "I believe that the lexical grammar is defined by the  
formal grammar in 4.2.1 modified by the rest of 4.2."

Why have a formal grammar that is then modified by informal text?  I  
had thought instead that the lexical grammar is defined by the formal  
grammar in 4.2.1, and that the rest of 4.2 is explaining the  
definition of the grammar (which is very different from modifying it).

I personally do not care how we resolve the issue of case sensitivity  
in these cases, but I think it is important that we resolve how to go  
about interpreting the R6RS in general.

Either there is a bug in the formal grammar, or we are going to agree  
to this method of interpretation where we informally modify the  
formal grammar.
