<!-- BNF Grammar block
  Use this tag to declare a fragment of a grammar specification.
  This sets the block within an indented region of text and changes
  the default font-style to use italic.

  Note that the spacing for the grammar is taken from the LaTeX
  version of the draft standard (or as well as I can interpret
  the spacing in LaTeX - a .9\textwidth minipage with tabs every
  .6 inches).
