It looks like it is WFS 1.0, judging by connection string supplied by
the IMS Service.
(http://localhost/wfsconnector/com.esri.wsit.WFSServlet/selected_feature
?request=getcapabilities&service=WFS&version=1.0.0)

If it helps, the WFS getCapabilities message is as follows:

<?xml version="1.0" encoding="UTF-8" ?>
