HTML5 is really Do you really mean "tag soup", or do you mean SGML based? Tag soup HTML has an ill defined, could be one level, parse tree and the early tag soup browsers tended to treat the tags, both open and close, as verbs (so got confused if, for example, they say <em> <em> </em> </em>). It generally doesn't have well defined rules as to where tags are not permitted. Valid, SGML HTML has a uniquely defined deep parse tree and conforms to a non-trivial grammar (that is more complex than XML DTDs can represent).
