Human-readable notation language

Section 5.2.3.16 (Notation Data) has this:

     First octet: 0x80 = human-readable. This note value is text, a
                         note from one person to another, and need
                         not have meaning to software.

To my reading, this says more or less, "this is a note from one person
to another except when it isn't".  Especially given such notations as
preferred-email-encoding(_at_)pgp(_dot_)com which are always human-readable, I
suggest this:

     First octet: 0x80 = human-readable. This note value is text.

It's just simpler.
