It's only my opinion, but I'd say there's not practical difference 
since both versions can be covered by the same DTD declarations:

<!ELEMENT one	((#PCDATA | two)*)>
<!ELEMENT two	(#PCDATA)>

Unless I'm mistaken, you could enforce a difference in SGML but in 
XML -- because of the enforced order of mixed content elements 
(see the declaration of element one) -- you aren't allowed to declare 
the distinction.
