xmlto is just a Bash-script, which uses xsltproc. So there error you get
is thrown by libxml/libxslt/xsltproc.

Can you give me the exact command you try execute? I would then try to
reproduce the problem myself. But please make sure, that xmllint is
happy with your files. ATM I guess, the validation fails. Also note the
--skip-validation switch. Does it run with this switch?
