Your call; if it’s an infrequent problem, we could commit it and leave a
FIXME in the code.  We could also use guile-yaml (or maybe some Go
code?) to parse it correctly.

So ‘xml->sxml’ isn’t good enough?  (If we can avoid the guile-lib
dependency, the better.)

To depend on Guile-Lib, you would:

  1. Add it to (guix self) — this is the code used by ‘guix pull’;

  2. Add it to the ‘inputs’ field of the ‘guix’ package;

  3. Maybe add a configure check in ‘configure.ac’, though it would be
     best if we could arrange to make it an optional dependency.

Yay, sounds promising!

Thanks,
