DITA - Multiple objects in anchored frame

Hi,

I'm using the DITA features in FrameMaker 9. I'd like to insert multiple objects in an anchored frame in a DITA topic.

Right now, if I save an image element containing multiple objects, FrameMaker discards any extra objects in the frame. I've also experimented with adding extra graphics elements to the DTD using the attributes listed in the Structure Application Developer Guide. I can save DITA topics containing the custom elements, but they are not added to the XML file though I can see them in the FrameMaker interface. I have not yet experimented with a DITA specialization.

When exporting anchored frames in Structured FrameMaker to XML, FrameMaker bundles multiple objects in a frame into a single CGM file.

Is there a way to export anchored frames to CGM files before saving DITA topics? Is there a plug-in out there that will automatically save the objects in a frame? Can I use read/write rules to define how to treat these frames? How about creating a specialization on the objects element?

I'd like to use the tools in FrameMaker to modify elements in an anchored frame. I don't see why doing this should break the DITA model if these objects are bundled into a single file on export.

Thanks,
- Maura
