[oXygen-user] Why does Oxygen 10 lock up when I add a schemaLocation to an XSD [SEC=UNCLASSIFIED]

Hi,

I am creating an XSD which looks like this:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema targetNamespace="http://www.isotc211.org/2005/gmd"
        elementFormDefault="qualified"
        version="0.1"
        xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns:xlink="http://www.w3.org/1999/xlink"
        xmlns:gmd="http://www.isotc211.org/2005/gmd">
 <!-- ================================= Annotation ================================ -->
  <xs:annotation>
   <xs:documentation> This file was generated from ISO TC/211 UML class diagrams == 01-26-2005 12:40:04 ====== </xs:documentation>
  </xs:annotation>
 <!-- ============================= Imports & Includes ============================= -->
 <xs:import nameSpace="http://www.w3.org/2001/XMLSchema" schemaLocation="http://www.w3.org/2001/XMLSchema.xsd"/>
 <xs:import namespace=" http://www.w3.org/1999/xlink"
        schemaLocation="http://www.isotc211.org/2005/xlink/xlinks.xsd"/>

 <xs:include schemaLocation="../gmd/metadataApplication.xsd" />
 <!-- ########################################################################### -->
 <!-- ########################################################################### -->
 <!-- ================================== Classes ================================= -->
</xs:schema>

As I create this XSD everything is fine until I add the schemaLocation hint of "http://www.w3.org/2001/XMLSchema.xsd". Oxygen then locks up. I have to use Windows task manager to delete the application.

What is wrong with identifying the XSD schema for a schemaLocation hint in a import statement?

Thanks.
