Examples of org.w3c.css.sac.CSSParseException

org.w3c.css.sac.CSSParseException
Encapsulate a CSS parse error or warning.
This exception will include information for locating the error in the original CSS document. Note that although the application will receive a CSSParseException as the argument to the handlers in the ErrorHandler interface, the application is not actually required to throw the exception; instead, it can simply read the information in it and take a different action.

Since this exception is a subclass of CSSException, it inherits the ability to wrap another exception.
