Question: I would like to allow the user of my XULRunner based app to be able to do copy/paste via a context menu.

Answer: 
You'll find your detailed explanation in the [iOS Developer Program User Guide](http://adcdownload.apple.com/ios/ios_developer_program_user_guide/ios_developer_program_user_guide__standard_program_v2.7__final_9110.pdf).
Go to developer.apple.com/ios, log in, look on the right for itunes connect, click on "manage apps", click "add new application" and follow directions for submission. You must be a registered apple developer and have already paid the developer fee.
