The docTypeDeclName exists specifically to state the root element type.

Think about what the code above means in *HTML*:
<HTML> <!-- implied -->
<BODY> <!-- implied -->
<P>This is a para</P>
</BODY <!-- implied -->
</HTML> <!-- implied -->
Now I suspect you understand why the docTypeDeclName exists and in XML
must always be the same as the type of the explicitly tagged root
element. Since XML has no minimization, it is redundant of course.
WebSGML allows you to use the keyword #IMPLIED (but XML does not) to
remove that redundancy.
