There is another workaround which is 100% W3C XML Schema which is to use
a "xsi:type" attribute instead of your unqualified "type" attribute:
"xsi:type" is a WXS feature that lets you specify the type (either
complex or simple) of an XML element in the instance document.
I don't know to which extend it is supported by XXE, though.
