So, in case it wasn't clear before, in my opinion the diagram as it
stands is not consistent with the definitions in the document; but it
can be made consistent just by drawing a box around the text I already
indicated.  Other than that, I think the diagram is useful.

It is possible to construct an argument that a bit string label could
happen to fall entirely inside the 7 bit range and not be an "ASCII
label" as such.  As far as I can see, there would be no way to tell
the difference between such a bit string label and an ASCII label, so
I don't grasp how the additional distinction will help understanding.
