Oh, so now I understand your way of parsing that line.

If anything, this makes a strong point of disallowing 'stray' >

Why should it be more or less valid in case c and/or d? If both are
containers, this line is simply incorrect. Either you start matching the
<bla> with the </bla> and notice that <blb> is not closed. Or you Start
with <bla>, recurse into <blb>...</blb> and notice that <bla> is never
closed.

Hm. Thinking my way the first </define-tag> would end the outmost
<define-tag>. Yes. I can see your point. I agree that d) ist most
probably better for this :)
