It's a good idea to keep unused bits reserved. Then we'll be compatible
with X.501 and save space a lot. I liked this.

If Trustin provides me a constructor that takes a String then i'll not
care if he uses your stuff or his own :-) But we should first be sure if
we'll use bit-list or bstring form. After Alex and Trustin says final
thoughts i'll finish it up.

( elecharny, i've fixed some issues with the grammar. I'll show you on the
channel. You can forget about issues of SP we talked here. )
