Attribute Definition inherited DxfObject, ICloneable, and IHasXData.
However, the Attribute Reference inherited DxfObject, and ICloneable.
The Attribute object is missing IHasXData interface. I added this and added the necessary items to the Attribute object so it can use XData. Furthermore, I modified DxfReader and DxfWriter to read and write XData from attributes.
