I tried online, for xhtml it does not do anything as I said in another
mail.  With xmlns added it does not do more.  For the regular html output, it
gives relevant output from the beginning of th efile, except that the files I
send seems to be truncated...  It shows that what is produced currently by
texi2any is far from being compliant with HTML5...

As for installing the validator, I'll wait for the validator to be
packaged in debien.
