Re: XSD to extend a "closed" schema

You may look also into NVDL. That allows validating the configuration 
file without your additional attributes against the initial schema and 
you can allow or validate your attributes against a schema that defines 
them.

A sample NVDL script that validates the configuration file and allows 
your attributes is below

<?xml version="1.0" encoding="UTF-8"?>
<rules xmlns="http://purl.oclc.org/dsdl/nvdl/ns/structure/1.0">
   <anyNamespace>
     <validate schema="official.xsd">
       <mode>
         <namespace ns="http://www.example.com/myeditor" match="attributes">
           <allow/>
         </namespace>
         <anyNamespace><attach/></anyNamespace>
       </mode>
     </validate>
   </anyNamespace>
</rules>
