Not sure exactly what you're asking, but this change was editorial in
nature only, as processing behavior continues to be specified (see the
2nd to last paragraph in Section 3.1.2 and 3.2.2.)

So the old text was informative only (and was taken from RFC6370).  The
new text is normative and says use definition from [RFC6370]. So I'm not
sure what is ambiguous in the new text.  What specific change would you
like to see?
