You don't declare element types more than once. Once is enough. Just 
remove the second declaration. And remove the TABs: as Joe pointed out, 
DTDs are not hierarchical (in fact the element type declarations can 
occur in any order so long as they satisfy all the necessary constraints 
by the end of the DTD :-)

You'll also need a root element type to enclose the whole thing, if you 
want your parentNode to occur more than once.
