- *
- * If any of the array's element key is "*", then the code treats all other key->value pairs as attributes, and the value['*'] as the element's content.
- * Example: name="root", value = array( "*"=>"text", "lang"=>"en", "id"=>10) creates <root lang="en" id="10">text</root>
- *
- * If neither key is found, all keys become element names, and values become element content.
