Here's the template I propose for use cases:

Title
   Keywords
   Goal and description
   Actors/stakeholders
   Assumptions
   Preconditions
   Main flow of events (Basic, alternate, exceptional)
   Postconditions
   Success requirements
   Special Requirements
   Issues
   Sources/references
   OGF sponsor/stakeholder/interested party
