Is it worth distinguishing between elements that can only contain PCDATA 
and elements that can contain both PCDATA and subelements?  I realize that 
the XML spec doesn't have separate terms for these, but in real life they 
are very different.  A PCDATA-only element is very close to an attribute, 
while an element containg PCDATA and elements is a very different beast 
altogether.
