Syntax Productions

These rules mainly use familiar notations:
*
for repetition, parentheses for grouping,
?
to indicate that the preceding construct is optional,
|
to separate alternatives. The rules are given in alphabetical order for ease of reference.

Simple tokens are represented using chevrons; for example,
@
in the first rule represents a literal at-symbol.
