* @todo implement an interface to allow for alternative implementations
* - make access to $_xh protected, return more high-level data structures
* - add parseRequest, parseResponse, parseValue methods
+ * @todo if iconv() or mb_string() are available, we could allow to convert the received xml to a custom charset encoding
+ * while parsing, which is faster than doing it later by going over the rebuilt data structure
