Indeed, I thought that the convention was similar to the C-c LETTER one, 
in which both lower and upper case letters are reserved for users, but you 
are correct, it's only upper case letters that are reserved for users in 
this case.  Which IMO isn't a good thing, typing C-x C-k S-LETTER is 
awkward.
