The EPP examples all set the language prior to a connect with

   epp_client.setLang("en");

However the language sent back with the greeting response is "en-US".

Page 15 of the EPP document indicates that "the values of the <version> and <lang> elements MUST exactly match one of the values presented in the EPP greeting."

In the examples, this doesn't appear to be the case, yet it also doesn't seem to matter.  After the greeting is returned, no additional setLang() call is made, as it seems it should be, to set the language element to "en-US".

Is this an implementation oversight?
