Tokens

The definition of a token that I am using here is: a symbol that cannot contain separating whitespace. This means that my classification of which symbols are tokens is slightly different from the classification that appears in the W3C specification.

Simple tokens such as
+
and
and
are not included in this table; they simply appear anonymously in the syntax productions.

DoubleLiteral	(( . Digit+ ) | ( Digit+ ( . Digit* )?)) ( e | E ) ( + | - )? Digit+	page 530
