例
<appInfo>
 <application version="1.5" ident="ImageMarkupTool1" notAfter="2006-06-01">
  <label>Image Markup Tool</label>
  <ptr target="#P1"/>
  <ptr target="#P2"/>
 </application>
</appInfo>

This example shows an appInfo element documenting the fact that version 1.5 of the Image Markup Tool1 application has an interest in two parts of a document which was last saved on June 6 2006. The parts concerned are accessible at the URLs given as target for the two ptr elements.
