Modify an existing reference by adding nested elements or (re-)assigning properties
mapped as XML attributes. This is an unusual task that makes use of Ant's internal
processing mechanisms to reload a previously declared reference by means of the 'id'
attribute, then treats the declared augment element as though it were the
original element.
Since Apache Ant 1.8.1
| Attribute | Description | Required |
