There are two different types of XML resources you can configure for
      WebLogic Server:
      
        - XML registries, which you use to specify alternative server-wide
        XML parsers and transformer used by WebLogic Server when it parses and
        transforms XML documents. You also use the XML registry to specify
        local copies of external entities and how to cache these
        entities.
- XML entity caches, which you use to configure the cache that
        WebLogic Server uses to cache external entities.
You can create as many XML registries and entity caches as you like;
      however, you can associate only one of each with a particular
      instance of WebLogic Server.
