I cannot find a reference to

	http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl

in the source code. (Or did I miss it?)

The "asciidoc" Guix package is patched so that it uses local docbook-xsl
instead of fetching the imports from the Internet.

xmlto, however, has the following file:

	/gnu/store/6932n73qc695c43fhqm1w213z65n7b7k-xmlto-0.0.28/share/xmlto/format/docbook/man

which content is

--8<---------------cut here---------------start------------->8---
case "$1" in
stylesheet)
  if [ "$VERBOSE" -ge 1 ]
  then
    echo >&2 "Convert to troff"
  fi
  echo "http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl"
  ;;
post-process)
  [ -e "$XSLT_PROCESSED" ] && rm "$XSLT_PROCESSED"
  ${GCP_PATH:-cp} -R -P -p -- * "$OUTPUT_DIR" 2>/dev/null
  ;;
esac
--8<---------------cut here---------------end--------------->8---

I think that "echo" line should be patched just like docbook.  What do
you think?

Yes, we should do something like what we do for docbook.

There are many packages using Docbook.  Often fixing the above issue is
just a matter of adding libxml2, libxslt, and docbook-xsl as inputs;
this has the effect of defining XML_CATALOG_FILES and related variables
such that things work.

There are also packages that directly modify the catalog URI, though I
can’t find a good example right now.

HTH!

Ludo’.

Adding ("libxml2" ,libxml2) to the native-inputs was enough.
Thanks!

That said, should we patch xmlto or leave it be?

If ‘xmlto’ uses libxml2, Docbook, and all that internally, perhaps we
could use ‘wrap-program’ to have it set XML_CATALOG_FILES directly.  I’m
not sufficiently familiar with it to make a well informed decision,
though.
