Mainly because DataTypes are nothing fancy, just beans that follow Ant's introspection rules. > 1) When were DataTypes introduce to ant, what release? In principle with Ant 1.2, but <typedef> didn't exist before Ant 1.4 (and didn't work properly before 1.5). > 2) What are the primary benefits of DataTypes? Re-use & References? In 1.6 there is a whole bunch of new opportunities for them, but let's stick with 1.5.x for now. I don't know of any benefit other than that you can define them outside of tasks. Any nested element can have an id and can thus be referenced. <fileset id="foo" ...> <copy ...> <fileset refid="foo"/> </copy> <copy ...> <fileset refid="foo"/> </copy> is mostly equivalent to <copy ...> <fileset id="foo" ...> </copy> <copy ...> <fileset refid="foo"/> </copy> > 3) Ought pretty much all NestedElement be DataTypes -- to be more > flexible?
