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).
