+Content model error:
+
+any-err-not-determinist-1.xsd:29: element complexType: Schemas parser error : 
+local complex type: The content model is not determinist.
+
+As per Xerces and XSV this schema is OK.
+
+The problem appears when the maxOccurs of <bar> is greater than
+the one of the <any> wildcard. Additionally if both are "unbounded".
+If the latter is a different issue we should add an explicit test
+for it.
+
+Examples:
+<bar>        <any>        result
+ 2            1           error
+ 2            2           OK
+ 1            2           OK
+ unbounded    2           error
+ unbounded    unbounded   error
+ 2            unbounded   OK
