Problem detecting XML

[Taylor, Wade]

Hi, I'm having trouble detecting a file as "application/xml". When I detect
a URL containing XML the detection works and I get "application/xml" as the
media type.

The output of running:

new Tika().detect(this.getClass().getResourceAsStream("/xml/sample.xml"))

is "text/plain".

And the sample.xml file is:

<?xml version="1.0" encoding="UTF-8"?>

<metadata xmlns="http://musicbrainz.org/ns/mmd-1.0#";>
    <release id="02232360-337e-4a3f-ad20-6cdd4c34288c" type="Album
Official">
        <title>Little Earthquakes</title>
        <text-representation language="ENG" script="Latn"/>
        <asin>B000002IT2</asin>
        <artist id="c0b2500e-0cef-4130-869d-732b23ed9df5" type="Person">
            <name>Tori Amos</name>
            <sort-name>Amos, Tori</sort-name>
            <life-span begin="1963-08-22"/>
        </artist>

            <event date="1992-02-25" country="US"/>

            <disc id="Y96eDQZbF4Z26Y5.Sxdbh3wGypo-"/>
        </disc-list>
        <track-list count="12"/>
    </release>
</metadata>

Is there something else I'm missing in order to detect a file as XML?

Thanks,
Wade
