That's invalid anyway, because you specify the root element type as 
being somedoctype, but then have an element called root. The two must 
match, eg

   <?xml version="1.0" encoding="utf-8" standalone="no"?>
   <!DOCTYPE somedoctype SYSTEM "http://www.someserver.com/
     somedoctype.dtd">
   <somedoctype>
   </somedoctype>

or

   <?xml version="1.0" encoding="utf-8" standalone="no"?>
   <!DOCTYPE root SYSTEM "http://www.someserver.com/
     somedoctype.dtd">
   <root>
   </root>
