------------------------------------------------------------
We need to do as much as we can on Tika to get file detection correct.
That said, I worry about letting a browser "execute" untrusted/user-supplied
files without much great controls in place.
To confirm, you want to allow (and execute) XML in the browser but not XHTML?
Are there other file types that you want to exclude (e.g. html, pdf, jpeg)?

> Project: Tika
> Issue Type: Bug
> Components: detector, mime
> Affects Versions: 1.27
> Reporter: Packiaraj Sakkanan
> Priority: Major
>
> mime-type of below xhtml file deduced as 'application/xml' instead of
> 'application/xhtml+xml'
> {code:java}
> <?xml version="1.0" encoding="UTF-8" ?>
> <script xmlns="http://www.w3.org/1999/xhtml";><![CDATA[
> alert(555);
> ]]></script>
> {code}
>
> one possible solution is to add 'script' in tika-mimetypes.xml, like
> {code:java}
> <mime-type type="application/xhtml+xml">
> <!-- The magic priority for xhtml+xml needs to be lower than that of -->
> <!-- files that contain HTML within them, e.g. mime emails -->
> <magic priority="40">
> <match value="<html xmlns=" type="string" offset="0:8192"/>
> </magic>
> <root-XML namespaceURI="http://www.w3.org/1999/xhtml"; localName="html"/>
> <root-XML namespaceURI="http://www.w3.org/1999/xhtml"; localName="script"/>
> <glob pattern="*.xhtml"/>
> <glob pattern="*.xht"/>
> </mime-type>
> {code}
