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.
appliedParameters  MFString    "BOUNCE"    
documentation
array of appliedParametersChoices. Note that strict validation of appliedParameters enumeration values does not occur via schema since MFString allows any value in any order.
