No, at least according to the XML recommendation.  However, it is
useful for character encoding information.  This is because the XML
spec says a document is [2]:

  document ::=  prolog element Misc* 

where prolog is [3]:

  prolog ::=  XMLDecl? Misc* (doctypedecl Misc*)? 

and XMLDecl is the XML declaration and Misc is comments, whitespace, or
processing instructions.

Great.  What fun...

On another note... the ".dtd" wasn't taken out of the xmlns in the
example in section 3.1. [4]  Furthermore, the contents at the top
number the subsections using letters, but the text gives them numbers.
