SSIS shows no coloumns in xml document in XML Source

I am trying to get the last date with exsisting exchange rates from National Bank of Belarus using their web service and SSIS. The XML file i receive from NBRB is quite simple:

<?xml version="1.0" encoding="utf-16"?>
<dateTime>2014-12-08T00:00:00</dateTime>

I generate XSD schema for this file in Visual studio:

<?xml version="1.0" encoding="utf-16"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://ift.tt/tphNwY">
    <xs:element name="dateTime" type="xs:dateTime" />
</xs:schema>

But when I try to use SSIS XML source to receive this data from the xml file, there is no dateTime coloumn in the Coloumns section.

Can anyone help me with this issue?
