XFoms 1.1 test 11.11.1.a.xhtml: soap:encodingStyle

I think I asked this before but we didn't decide; why is there a soap:encodingStyle attribute on the html element in this test?
It's nothing to do with XForms, as far as I can tell.

Leigh,


I get
11.11.1.a.xhtml:8:65: cvc-complex-type.3.2.2: Attribute 'soap:encodingStyle' is not allowed to appear in element 'xhtml:html'.

where the text alluded to is
<xhtml:html xmlns:ev="http://www.w3.org/2001/xml-events" 
xmlns:xforms="http://www.w3.org/2002/xforms" 
xmlns:xhtml="http://www.w3.org/1999/xhtml" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">


Do we need to support attributes such as soap:encodingStyle on HTML?  What other SOAP attributes are needed for which elements?
