It means you're misunderstanding the word "should" :-)

You properly understand what is being discussed--your example is
a case in point that, for interoperability, *should* not occur.
(This is because such stuff is illegal in pre-WebSGML SGML.)
However, "should" doesn't mean "must not."

I'm not sure what the various parsers would say about your code.
They shouldn't give an error, but they may give a warning (or
they may just quietly handle it).
