  no :-) . Well formedness is tested just by running
    xmllint --noout file.xml

and only well-formedness errors will be printed there, and possibly some
warning (which can be suppressed with --nowarning).
Then validity can be checked against the DTD (--valid or --dtdvalid),
or XSD and Relax-NG (see xmllint help), but that doesn't seems to be the
question.
