3.6.2 Protogate Definition Language (PDL) Grammar
The following extended BNF metalanguage describes the language used to create the TSI
text configuration file. The following is a brief description of the symbols used:
1. A string inside of <> is a non-terminal symbol. Its definition is located somewhere
down the list.
2. Strings inside of {} separated by a vertical bar (|) make up a list of options. You can
select one or none of the options.
3. A string inside of [] is an optional string.
4. Terminal symbols are those not surrounded by <>.
