>From an XSD point of view, xs:any should be fine, perhaps nested within an 
element.  e.g.

<xs:element name='nonValidated'>
    <xs:complexType><xs:sequence>
        <xs:any namespace='##any' processContents='skip'
            minOccurs/maxOccurs etc. />
    </xs:sequence>...

The fact that it is not being used as an extension is not an issue.  For 
example, one use-case of this sort of thing is including chunks of XHTML 
within an XML file.
