Export ECore to XSD [message #1855765]

I'd like to export an Ecore Model in Eclipse to a XML Schema Definition.
Using the default export mechanism "XML Schema to XMI" works just quite fine but ExtendedMetaData annotations are not considered (//org/eclipse/emf/ecore/util/ExtendedMetaData)!

How can I generate a XSD including ExtendedMetaData (like minInclusive for java.lang.Integer) using the XMI datatypes to get something like below?

<xs:simpleType>
      <xs:restriction base="xs:integer">
         <xs:minInclusive value="42"/>
      </xs:restriction>
</xs:simpleType>

The generated schemas are in general useless, e.g., XML Schema doesn't support multiple inheritance but Ecore does, XML Schema supports a limited set of data types but Ecore supports and unlimited set. I do not have the resource to invest in enhancing the exporter to be somewhat less useless in those limited cases where that's even feasible...
