<!-- relaxng.dtd

     Based on grammar in section 3 of RELAX NG 1.0 (3 December 2001), which
     made this very easy to put together. While entity declarations such as
     those for param, start, and define may look redundant, I wanted this to
     reflect the BNF grammar as closely as possible.
