Implements the abstract part of an element. By default elements
support attributes by having a field that represents the immutable
part of the current attribute set for the element. The element itself
implements MutableAttributeSet which can be used to modify the set
by fetching a new immutable set. The immutable sets are provided
by the AttributeContext associated with the document.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans
package.
