Get the description object.
You may use $selector to force a given class to be instantiated. If you set $selector=ISTER_UI_USE_NATIVE, the IsterUI*DescExpatNative classes are used. These are about 10% faster and less memory expensive. If you plan to use one of the non-native classes of the xml package elsewhere, you may not use the native classes here because this would lead to even more memory consumption due to doubled loading of classes.
object IsterObject getCloned(
mixed
$type, mixed
$class)

Get a description of the same group like $class is in.
For example, if $class is one of the ISTER_UI_USE_NATIVE classes, the returned class will also one of these classes. Used to create description chains.
