Class Overview

This is the base class of all date/time datatype validators. It implements common code for parsing, validating and comparing datatypes. Classes that extend this class, must implement parse() method. REVISIT: There are many instance variables, which would cause problems when we support grammar caching. A grammar is possibly used by two parser instances at the same time, then the same simple type decl object can be used to validate two strings at the same time. -SG
