lib/rouge/demos/xml is not valid XML

[voxik]

It seems that the lib/rouge/demos/xml is not valid XML:

$ xmllint lib/rouge/demos/xml
xml:2: namespace error : Namespace prefix xsl on template is not defined
<xsl:template match="/"></xsl:template>
                       ^
<?xml version="1.0" encoding="utf-8"?>
<xsl:template match="/"/>
