text: In XML, the definition and syntax of the markup language are defined in a*schema file*. For the 
  Content Manager OnDemand XML batch program, the schema file is called ondemand.xsd. It 
  contains the definitions for the Content Manager OnDemand objects: users, groups, 
  applications, application groups, storage sets, folders, printers, and others. Each Content 
  Manager OnDemand object definition contains one or more child objects. For example, a user 
  object has a child object for permissions, and a group object has a child object for users in the 
  group. The schema file (ondemand.xsd) must not be changed in any way by the user. 
  
  The*input XML file*for the XML batch program is parsed to ensure that it is valid according to 
  the schema file. Each object within the file is examined to ensure that the attributes are valid 
  according to the object type. The XML batch program generates XML when Content Manager 
  OnDemand objects are exported. The XML that is generated can be used as an input for the 
  subsequent**arsxml**command. 
  
  Example 3-1 shows a sample of the file exportusers.xml from the XML samples directory. 
  You can change the names of the users to the users that you want to export.
