Actually, external DTD subsets, external parsed entities, and external 
parameter entites do not have to begin with "<".  In particular, 
external parsed entities can begin with any character.  To allow 
autodetection, XML 1.0 requires that external parsed entities must begin 
either the BOM or text declarations, if not in UTF-8.
