attributes
Name  Type  Use  Default  Fixed  Annotation
DEF  xs:ID        
appinfo

DEF defines a unique ID name for each node, referenceable by other nodes.
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.
