    public class XML
extends AbstractOutput
    Outputs the predictions in XML.

    The following DTD is used:

    <!DOCTYPE predictions
    [
    <!ELEMENT predictions (prediction*)>
    <!ATTLIST predictions version CDATA "3.5.8">
    <!ATTLIST predictions name CDATA #REQUIRED>

    <!ELEMENT prediction ((actual_label,predicted_label,error,(prediction|distribution),attributes?)|(actual_value,predicted_value,error,attributes?))>
    <!ATTLIST prediction index CDATA #REQUIRED>

    <!ELEMENT actual_label ANY>
    <!ATTLIST actual_label index CDATA #REQUIRED>
    <!ELEMENT predicted_label ANY>
    <!ATTLIST predicted_label index CDATA #REQUIRED>
    <!ELEMENT error ANY>
    <!ELEMENT prediction ANY>
    <!ELEMENT distribution (class_label+)>
    <!ELEMENT class_label ANY>
    <!ATTLIST class_label index CDATA #REQUIRED>
    <!ATTLIST class_label predicted (yes|no) "no">
    <!ELEMENT actual_value ANY>
    <!ELEMENT predicted_value ANY>
    <!ELEMENT attributes (attribute+)>
    <!ELEMENT attribute ANY>
    <!ATTLIST attribute index CDATA #REQUIRED>
    <!ATTLIST attribute name CDATA #REQUIRED>
    <!ATTLIST attribute type (numeric|date|nominal|string|relational) #REQUIRED>
    ]
    >
