Item cannot reconstruct XML with CDATA

[apandichi]

Given the following XML:

<?xml version="1.0" encoding="utf-8"?>
<root>
    <![CDATA[<?xml version="1.0" encoding="utf-8"?>
    <CurrentWeather>
        <Status>Success</Status>
    </CurrentWeather>
    ]]>
</root>

Parsing this XML into an Item instance, and then calling getElementAsString() on it, will result in a malformed XML that is missing the wrapper.

Please see a testcase here: apandichi@311767b
