Issue with Dublin Core dcterms

Hi,

tried to test this http://dublincore.org/schemas/xmls/qdc/2008/02/11/dcterms.xsd
with xsd-forms Generator and following error occurs:

java.lang.RuntimeException: unsupported TopLevelElement(None,None,List(),None,Some(title),None,None,Some({http://purl.org/dc/elements/1.1/}title),1,1,None,None,false,false,None,None,None,Map())
at com.github.davidmoten.xsdforms.tree.Util$.unexpected(util.scala:23)
at com.github.davidmoten.xsdforms.tree.SchemaTraversor.process(traversor.scala:145)

...

Is that something that could be easily fixed (for example by modifying the XSD) or could it be a bug?

Thanks,
Mikael

Reproduce the failure with the linked dcterms.xsd and xsd-forms Generator, then start at SchemaTraversor.process in traverser.scala:145 and Util.unexpected in util.scala:23. Determine why the schema's title TopLevelElement is unsupported; done means the generator handles this schema without the reported RuntimeException.
