I forked schema2src, an XML data binding tool for scala, to work on xsd feature at github. It's still work in progress, but it now generates code that binds against scala.xml.Node object.
From the the xsd schema, I get the scala code.
<xsd:complexType name="Items">
<xsd:sequence>
<xsd:element name="item" minOccurs="0" maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
