Those components/resources that apply to all types of renderers, can be

AbstractRenderer could provide a generic createResource() method, which
can be overridden or re-implemented in the specific renderer types to
handle the renderer-specific stuff.
Coming to the Intermediate Format: that document should, as you
mentioned earlier IIRC, ideally be renderer-agnostic. So, if all is set
up well, the resources can be embedded/referenced in the intermediate
document as abstract <resource> nodes, with a reference (attribute?) to
the applicable renderers. Some resources may have to be inserted
multiple times for different renderers? So be it. The IFHandler should
probably be made intelligent enough to ignore/ disregard any nodes that
do not apply to the current output format, so they get excluded real
early in the game. When the document is ultimately rendered, the
eventual renderer type will determine what needs to happen with the
The downside to including a resource node for each possible renderer is
the space occupied by the Intermediate Format. The major problem with
the current IF XML is how verbose it is. This verbosity is what makes
the performance of FO->IF->PDF so slow. This is the main driver for
re-working the current implementation.
