No, Ci can be a subtype of Ti.  "More specific" means "descendant from".

This is LEW we're talking about. Every other word he posts is a 
quotation from the JLS. He sleeps with a dog-eared copy of the JLS under 
his pillow. It's probably what he masturbates to.

And though he sometimes loses patience with those of us that don't have 
it memorized backwards and forwards, his JLS-informed advice in this 
newsgroup is frequently useful.

Gee, you rebut his opponent and somewhat compliment the guy, and this is 
the thanks you get?

With you so far, but ...

This seems to be a complete non sequitur. Except maybe for that last part.

Maybe someone needs to smack Lawrence upside the head with a bound and 
printed copy of the JLS.

Well, isn't that special?

I suppose you thought that was pretty clever when you wrote it.

One of the reasons I reread the JLS so often is that I don't memorize it, and 
some of the passages are a bit thick.  As for my citations, that doesn't 
require any special skill.  You just see a question about Java syntax or 
semantics, and you think to yourself, "Hey, let's see what the JLS says about 
that!"  Then you look it up.  That'll make you an instant expert on most of 
those questions.

As for "Lawrence"'s remark, it is quite clear that evidence or reason for it 
were not foremost in his mind.  He ain't nothin' but a hound dog.  He ain't 
never caught a rabbit, and he ain't no friend of mine.

Really? Then he would know how the language spec uses the word “descendant”.
