Are you uncertain as to which unit_type would be used in which unit in the
examples (after having read Section 7)? Or is it that you know the answer
now, and it would've been easier/faster to find if the examples had been
more explicit?

(it seems there's limited ambiguity from section 7 - such that the examples
don't need to clarify much in this regard, but yeah - seems OK to me that
they could describe the header now that the header's a bit more complicated)
