You can use Before and After pages for different purposes. You can, for example, use a Before page as a cover sheet. You can create as many Before and After pages as you like. The pages will be added to the output in the same order as you create them in the PageOUT tool. Note that Before and After pages cannot contain frames.
You can use variables below the root node in the Message view, and variables created by before Message or before Process scripts. For example, you can use these variables together with the
Skip function to select different Before pages.
