Hi, I want to propose the following change to man_validate.c - if we are missing SOURCE and VOL in TH, do the same as for the mdoc manpages - use OSNAME, if it's not defined, use uname output and get the VOL from msec.in if VOL isn't defined in manpage. I've attached the diff that seems to work for me (mostly just copy/paste from mdoc_validate.c), hope the idea sounds ok.. Yuri
