Quoting Pierre R. Mai (pmai@pmsf.de):
Previously cxml:parse-file would cause an error in pathname-to-uri when handed a pathname with :back or :up entries in the directory component. This change ensures that a suitable base-uri is generated in those cases.
Thanks. I'm not entirely sure that leaving .. in pathnames is the right thing either, but it's better than an error, so I have committed that patch to git.
