should contain_xml not working

[pzol]

   the xml:
    <hotels destination_code="MAD" language="de">
              <geo lat="40.419" lon="-3.706" />
   </hotels>

   should match xml:
        <geo lat="40.419" lon="-3.706" />

returns false, it should return true for contain_xml
Besides... the description of the failure message should be "should contain xml"

According to the test file this is not supposed to work: https://github.com/alovak/test_xml/blob/ab6c2d6ac4bbbf315eceeb680e0e96f4470752d0/test/test_unit/test_assertions.rb

However, "contain" implies that we're only interested in a contained markup fragment, right? Currently, the assertion tests if any of the contained nodes are within the expected markup. So, what is the expected behaviour of "contains"?
