I don't think there's any such thing as "invalid Markdown."
At any rate, the syntax description does not define anything as
"invalid". And markdown processors (at least those that I'm
familiar with) don't ever give you an "invalid markdown" error.

But if you don't like that example, consider this one:


Should this be



<emph><strong>hello</strong></emph> ?

Nothing in the spec settles that. This is just one of many, many
examples one can come up with by considering precedence ambiguities.
