The conventions use different font attributes for different components of the syntax. The symbols and fonts are as follows:
| Attribute |
Description |
| nonterminal |
Italic type indicates nonterminals. |
| #include |
Terminals in bold type are literal reserved words and symbols that must be entered as shown. Characters in this context are always case sensitive. |
| opt |
Nonterminals followed by opt are always optional. |
| default typeface |
Characters in the set described or listed in this typeface can be used as terminals in statements. |
A colon (:) following a nonterminal introduces its definition. Alternative definitions are listed on separate lines.
