Examples of ExtensionAttachment

org.apache.fop.fo.extensions.ExtensionAttachment
This interface is implemented by objects that are returned by special extension element through the FONode.getExtensionAttachment() method. Such objects are carried in the FO tree and made available to the layout managers that support processing extension attachments or support passing them on to the area tree where they can be picked up by renderers.
NOTE: Classes which implement this interface need to be Serializable!
