each tag generates a new instance of the class

you can add a property (that all objects have) called InstanceName

<option instancename="blabla">something</option>

using the instance name the class factory can differentiate from other
instances (factory.instance['blabla'] retrieves the correct instance,
or, factory.dotnotation['roottag.nexttag.blabla'] retrieves by dotted


if you dont specify an instance name the factory will generate one randonly...

and actually i prefer to setup properties of objects using xml
properties instead of xml text

<tcpserver ip="" port="80"/> instead of
