When authoring this can also be a problem.
You might have a large module (ASN.1, XDR, ABNF, whatever) and you need
to a) scatter it throughout the document so that the English prose can
be read in context, b) gather it all into one appendix, c) be able to
extract or inject the module so you can work on it outside the I-D
(e.g., because the two are evolving).
This is a bit pain. It's the reason that RFC4120 was edited in nroff,
Keeping the canonical module scattered is not an answer.
Addressing parts (of a canonical module in an Appendings) by line number
Annotating the module with anchors and start/end markers for extraction
would require that the processor understand that markup in the figure,
though at least the markup wouldn't have to be specific to the module
language. OR it would require breaking up the module into multiple
CDATAs so that this markup can be XML (of course), but this is a PITA
I don't have great answers.
