Help wanted with XML Schema for Dublin Core in RDF/XML

I'm the editor of 
  Expressing Simple Dublin Core in RDF/XML  
  http://dublincore.org/documents/dcmes-xml/

which is a draft document for the Dublin Core Metadata Initiative
The latest version 2001-11-28 is at
  http://dublincore.org/documents/2001/11/28/dcmes-xml/

In earlier versions I added an XML Schema to an appendix, to go along
with & derived from the DTD.  We've received various feedback on
these schemas during the process, but I'm no expert on XSD.  The
latest suggestions we got on the 2001-11-28 schema are particularly
difficult for me to answer:

  Remove the <import>s of http://www.w3.org/XML/1998/namespace and
  http://www.w3.org/2000/10/XMLSchema as they aren't required - "over
  the top" and may cause performance problems with tools.
    -- I thought these were required for validation

  Revert the schema to the older one, without the any and
    anyAttribute stuff 

I really don't know how to evaluate these or fix other problems that
may be there in the schema.  Any help would be appreciated

Thanks

Dave
