That seems reasonable.  But, there are various kinds of markers for
trails I have encountered, and some of them would not necessarily be
called blazes.  I've seen:

  painted rectangles on trees
  plastic triangles nailed to trees
  1.5"x3"x0.75" painted blocks nailed to trees
  (all of these qualify as blaze)


  piles of rocks, where there are no trees ("cairns")

I'm not sure if cairns count as blazes in hiking parlance.  But it seems
fair enough to call them that, and it makes sense to have



This feels like overkill, but I have been putting 'name=yellow' on
trails that have yellow blazes and no name, because it's useful (even if
a bit off) and because people call that "the yellow trail".
So I would expect you to have two nodes (next to each other) when there
are two blazes.

I would expect the purpose can be

  blaze inventory by the trail maintenance group

  producing a map with the trail's colors labeled and also showing
  little marks for the blazes.
