In the org.eclipse.wst.xsd.ui plugin, there's an extension that adds some XML 
schema to the XML catalog:

<extension
  point="org.eclipse.wst.xml.core.catalogContributions">
  <catalogContribution id="default">
    <uri
      name="http://www.w3.org/2001/XMLSchema"
   uri="platform:/plugin/org.eclipse.xsd/cache/www.w3.org/2001/XMLSchema.xsd" />
  </catalogContribution>
</extension>

If you look at this extension closely, you'll see that the location of the XML 
schema is specified as a platform URI. This works if the org.eclipse.xsd plug-
in is distributed as an "expaned" plug-in. However, EMF has recently single jar-
ed all their plug-ins, so this platform URI mechanism no longer work in the 
development environment. The result is an error message in the problems view:

Referenced 
resource 'platform:/plugin/org.eclipse.xsd/cache/www.w3.org/2001/XMLSchema.xsd' 
in attribute 'uri' cannot be found.

I'm not sure whether this works in the run time environment or not. Can someone 
test this? A possible solution to this problem is to include the schema in the 
org.eclipse.wst.xsd.ui plug-in. Obviously, this requires Eclipse foundation's 
approval.
