lower-case tag names allowed?

lower-case tag names allowed?

[Wolfgang Gehrke]

Hello,

the top level tells me:

        Objective Caml version 3.00
 
# let test1 = `A;;
val test1 : [> `A] = `A
# let test2 = `a;;
val test2 : [> `a] = `a

on the other hand the manual says:
Variant tag = uppercase (tag-name ::= capitalized-ident)

Personally I like to have both possibilities, but I would not like to
rewrite the code in the future. In fact one can bounce into a keyword
(let test = `method;; fails).
What is correct?

Thank you,
Wolfgang
