DITA is just a way to store the structured content and as such has no built-in tools to make anything appear in heaers or footers of a PDF document. Simply because DITA is only the content, and everything else needs to be created from either the DITA source itself or from external sources of information. Still, you can use FrameMaker's rendering capabilities to pick up some text that will have to be inside your DITA file and show it as part of the header and footer via Running H/F variables. I would suggest creating a special paragraph format that uses 2pt font size, 0 pt fixed linespacing, no space above and below, and white font color (so that it becomes invisible on the content pages and takes up no space in your layout. With the ditaval files, you can control the content of this invisible paragraph. Make sure it is at the start of your topic, e.g. as a titlealts element following your title. Then define your template with Running H/F variables to pick yp the content of the titlealts paragraph. In this way, all the content is part of the DITA file, even though some content is not visible as such, but only created to style the header and footer of your pages.
