USE  xs:IDREF        
appinfo

                    USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).
               
class  xs:NMTOKENS        
appinfo

                    The class attribute is a space-separated list of classes, reserved for use by Cascading Style Sheets (CSS) and XML stylesheets.
