No, but the second one overlaps with the range value shown in 8.17.2.
So this is correct if it's understood as a continuation of that example.
Still, it's kind of a long way from 8.17.2 to 8.17.10. It might be better
if this section were recast to use a standalone example --- Jeff, what do
you think?
