You could easily implement a FOP extension (for example as child of fo:declarations) to transport the names of the files you want to embed through the layout engine to the PDF renderer. Here's the list of things to build:
- Implement a new subclass of FONode for the extension object and be sure to override getExtensionAttachment(). An example is org.apache.fop.render.ps.extensions.PSSetupCodeElement. The ExtensionAttachment is what's transported through the layout engine. - The extension object has to be registered with an ElementMapping class (depending on which namespace you want to place the extension in). - Extend the PDF library so it can produce an "EmbeddedFile" structure and so the "EmbeddedFiles" name tree is added to the "Names" object (as per the PDF spec). - Extend the PDF renderer to accept and evaluate the ExtensionAttachment so it generates the respective PDF objects. This would be done in PDFRenderer.processOffDocumentItem(). Have fun.
