| 2 | +<!-- BNF Grammar block |
| 3 | + Use this tag to declare a fragment of a grammar specification. |
| 4 | + This sets block within an indented region of text and changes |
| 5 | + the default font-style to use italic. |
| 6 | +
|
| 7 | + Note that the spacing for the grammar is taken from the LaTeX |
| 8 | + version of the draft standard (or as well as I can interpret |
| 9 | + the spacing in LaTeX - a .9\textwidth minipage with tabs every |
| 10 | + .6 inches). |
| 11 | +
|
| 12 | + FIXME: We should pobably define a CXX class for these blocks. |
