It should probably say > "called" instead of "evaluated", too. First I think you should use "substitution", not "value", because that's how the SPECIFICATION alist is described: SPECIFICATION is an alist mapping format specification characters to their substitutions. And then I'd suggest something like If the substitution for a specification character is a function, the function will be called only if FORMAT uses that character.
