I've seen the XML Schema Type Library's "text" type,
supporting arbitrary mixed content. I have been unable to figure out how
to define a complex type whose contents are any simple type value or any single
element, but not a mixture, where an element of this special type has a certain
set of attributes That is, I'm trying to define
<element name="foo">
<complexType >
??? some kind of restriction of anyType with
either simple or complex content
<restriction base="anyType">
???
<attribute name="a"
...>
<attribute name="b"
...>
</restriction>
???
</complexType>
</element>
so I can say in instance docs
<fooList>
<foo a="x" b="y"
xsi:type="xsd:boolean">true</foo>
<foo a="xx" b="yy"
xsi:type="SomeComplexType">
<someComplexType>...</someComplexType>
</foo>
...
</fooList>
I think I need a disjunction of simpleContent and
complexContent but am uncertain how to produce this.
