Apache Ant AntStructure Task
This task is used to generate a DTD for Ant buildfiles. It contains information about all tasks currently known to Ant.
We can always add XML entities using <taskdef> or <typedef> elements. This task doesn't know about required attributes.

AntStructure Task Example
We can simply use it using <antstructure> element by specifying output file. See the example below.

and then we can use it via typedef element.
