CSS::DOM::Exception - The Exception interface for CSS::DOM

       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 'EXPORTS').

       The following constants are optionally exported. The descriptions are copied from the DOM spec.

       INDEX_SIZE_ERR (1)
           If index or size is negative, or greater than the allowed value

       DOMSTRING_SIZE_ERR (2)
           If the specified range of text does not fit into a DOMString

       HIERARCHY_REQUEST_ERR (3)
           If any node is inserted somewhere it doesn't belong

       WRONG_DOCUMENT_ERR (4)
           If a node is used in a different document than the one that created it (that doesn't support it)

       INVALID_CHARACTER_ERR (5)
           If an invalid character is specified, such as in a name.

       NO_DATA_ALLOWED_ERR (6)
           If data is specified for a node which does not support data

       NO_MODIFICATION_ALLOWED_ERR (7)
           If an attempt is made to modify an object where modifications are not allowed

       NOT_FOUND_ERR (8)
           If an attempt was made to reference a node in a context where it does not exist

       NOT_SUPPORTED_ERR (9)
           If the implementation does not support the type of object requested

       INUSE_ATTRIBUTE_ERR (10)
           If an attempt is made to add an attribute that is already inuse elsewhere

       INVALID_STATE_ERR (11)

           If an invalid or illegal string is specified

       INVALID_MODIFICATION_ERR (13)
           If an attempt is made to modify the type of the underlying object

       NAMESPACE_ERR (14)
           If  an  attempt  is  made  to  create  or change an object in a way which is incorrect with regard to
           namespaces

       INVALID_ACCESS_ERR (15)
           If a parameter or an operation is not supported by the underlying object

       new CSS::DOM::Exception $type, $message

           constants listed under 'EXPORTS').  $message is the error message.
