Xml output

My method

Code:

function connector()
    {
$data='<data>
    <event id="3">
        <start_date>2010-07-28 00:00:00</start_date>
        <end_date>2010-07-28 16:00:00</end_date>
        <text>&lt;![CDATA[Demo]]></text>
        <details>&lt;![CDATA[The Queens Club London, ENG]]></details>
    </event>
</data>';
header('Content-type: text/xml');
echo $data;
    }

returns

<data>
<event id="3">
<start_date>2010-07-28 00:00:00</start_date>
<end_date>2010-07-28 16:00:00</end_date>
<text>Demo</text>
<details>The Queens Club London, ENG</details>
</event>
&lt;style/&gt;
</data>

I can't figure why "&lt;style/&gt;" is in the output O_O
Hints?
