judyr Mutation represent the changes which can be made to the xml object model when the user interacts with the interface. You can either add or delete an element. If adding and element, you can add an attribute or some new content. A new attribute can have a name and a value associated with it. To modify an attribute in an existing element, add an attribute with the same name with the new value and it will replace the old attribute. When adding content, you can either add a new textual value for the element, or give it a new child by specifying the id of the new child This design is taken from Jonathan Kilgour's document "Actions within the NITE GUI specification" written on 26/03/02
