  Modified:    v1/external/lib oldxbean.jar
               v1/src/typeimpl/org/apache/xmlbeans/impl/schema
                        StscImporter.java StscState.java
               v1/src/xmlcomp/org/apache/xmlbeans/impl/tool SchemaCopy.java
               v1/src/xmlpublic/org/apache/xmlbeans XmlOptions.java
               v1/src/xsdschema/schema XMLSchema.xsd
  Log:
  This change fixes two things:
  
  (1) It adds an "EntityResolver" option (see org.apache.xmlbeans.XmlOptions)
  that is used by the Schema compiler to resolve URL references.  This allows
  folks to define their own URL schemes, etc.  Very simple to do, yet wildly
  useful for lots of tricks.  We treat namespace URIs (when applicable) as
  publicIDs on the EntityResolver/InputSource interfaces.
  
  (2) It makes a minor update to XMLSchema.xsd to bring it up-to-date with
  the latest on www.w3.org.  I've also posted on xmlschema-dev@ to tell them
  about the problems we've found+fixed.
  
  Code review: eric vasilik
  Bootstrap: passed
  Regression tests: passed
