I am not totally clear on the semantics of upper-case() and lower-case().
Are they suppose to implement full case mappings (as is strongly suggested by:
"Case mappings may change the length of a string."), or simple case mappings?
It would be nice to explicitly say that the full default mappings must be used.
It think it would also be good to add a warning that
lower-case ($A) eq lower-case ($B) is not a true case-insensitive comparison
(for that we would need a fold-case() function, but I'm not suggesting taht be
added for 2.0 at this late stage).
