* This expression represents a date represented in JDBC escape syntax, for instance, the String:
* {d '1901-01-01'} can be used to represent a Date and use used only by the JPQL parser.
*
* This is different from a ConstantExpression because this value is never converted with the conversion
* manager and is printed out as-is
*
* The only validation for this type of expression will be from the JDBC driver.
