Description

Date literal represents a date type literal value. It's BNF grammar as follows:

<date literal>    ::=   DATE <date string>
<date string>    ::=   <quote> <unquoted date string> <quote>
<unquoted date string>    ::=   <date value>
<date value>    ::=   <years value> <minus sign> <months value> <minus sign> <days value>
