Referring to Chapter By Number

[iwelch]

I use markdown for writing books now. The main output targets are latex's book and the epub format, as well as html (which numbers chapters only by virtue of a style file). Because the writing in some places needs to refer to earlier chapters ("In Chapter X, ..."), I need to refer back to number X, aka \label{} and \ref{} in LaTeX. I know that the pandoc-xnos tools provide this kind of facility. Is this the recommended solution now, or is there some mechanism built into base pandoc?

No, there's nothing built in that does this. (For LaTeX you can just use \ref, but that won't be portable to EPUB.)

It would be possible to create a filter that handles this, but if pandoc-xnos does it, why reinvent the wheel.

I've been hacking away at querverweis, as I needed a filter that doesn't require python. Another motivation was that pandoc-xnos appears to be unmaintained right now.
