This module implementations the W3C's DOMException 
interface.
CSS::DOM::Exception objects
stringify to the message passed to the constructer and numify to the 
error
number (see below, under '\s-1EXPORTS\s0').

.IX Item "new CSS::DOM::Exception $type, $message"
This class method creates a new exception object. \f(CW$type\fR is expected to
be an integer (you can use the constants listed under '\s-1EXPORTS\s0').
\&\f(CW$message\fR is the error message.
.SH "EXPORTS"
