<?php
  $xml_elements = array(
    array(
      'key' => 'key1',
      'value' => 'value1',
    ),
    array(
      'key' => 'key2',
      'value' => 'value2',
    );
    array(
      'key' => 'key3',
      'attributes' => array(
        'attrib1'  => 'this attribute',
        'attrib2' => 'that attribute',
        'attrib3' => 'the other attribute',
