Description:
 def parseExtensionArgs(self, args, strict=False):
 """Parse the unqualified simple registration request parameters and add them to this object. This method is essentially the inverse of C{L{getExtensionArgs}}. This method restores the serialized simple registration request fields. If you are extracting arguments from a standard OpenID checkid_* request, you probably want to use C{L{fromOpenIDRequest}}, which will extract the sreg namespace and arguments from the OpenID request. This method is intended for cases where the OpenID server needs more control over how the arguments are parsed than that method provides. @param args: The unqualified simple registration arguments @type args: {str:str} @param strict: Whether requests with fields that are not defined in the simple registration specification should be tolerated (and ignored) @type strict: bool @returns: None; updates this object """
