What is POLA?

I strongly disagree.  In my mind innermost tags must be closed first.
So here is another question, which one is preferred?
 c) first open, first close
 d) last open, first close

My preferred one is (d) (and to be honest i never thought of (a) before)
because it prevents nesting problems, e.g.
  <define-container bla>%body</define-container>
  <bla><blb></bla></blb>
is valid with (c).

And it allows
  <define-tag foo>
    Before definition: <bar>
    <define-tag bar>
      baz
    </define-tag>
  After definition: <bar>
  </define-tag>
