*
* It's also possible to mix 'value-only' and 'non-value-only' elements in the array.
*
* <things>
* <option id="option1" value="value1">
* <option id="option2" value="value2" foo="foo2">
* </things>
*

* 'option2' => array(
* 'value' => 'value2',
* 'foo' => 'foo2'

*
* <things>
* <option id="option1">

* <foo>foo1</foo>
* <bar>bar1</bar>
* </value>

* 'foo' => 'foo1',
* 'bar' => 'bar1'
* )
* )
* )
*
* If using VariableNode for value node, it's also possible to mix different types of value nodes:
*
* <things>
* <option id="option1">
* <value>
* <foo>foo1</foo>
* <bar>bar1</bar>
* </value>
* </option>
* <option id="option2" value="value2">
