This validation framework does not implement the JSR-303 specification. The main features of this implementation are:

• Ability to modify (correct) test values.
• Support for validation of localized values.
• Conversion of values into and from text representation.
• Formating of error messages, depending on the context.
• Support for metadata, which allows to check any entity types.
• Long list of predefined validation components.
• Good opportunities for expansion.
