Few questions about Stored outlines

Hey All,  

I had a few questions regarding stored outlines that I was hoping someone could help me answer.  

1. If your application mainly uses packages and procedures for everything, what is the best way to create stored outlines? For outlines that are not being created for code being executed within procedures.
2. Are there any restrictions of stored outlines being moved across versions? For example, can I export the outlines from a 9i database and load them into a 10g database.
3. Does anyone have any recommendations for good sources of info for stored outlines outside of what can be found in the manual or Metalink

Thanks
