It is a typo in practical terms and should be fixed, but it is
not a syntax error with respect to the formal rules, and a
validator's job is to check conformance to those rules, and only that.

The construct </OL<P> is formally valid (and equivalent to </OL><P>) due
to so-called short-hand
markup rules, see
http://www.w3.org/TR/html4/appendix/notes.html#h-B.3.7
for an informal explanation, and SGML documentation for rigorous rules.

Browsers generally do not support short-hand markup, which on the other
hand is what HTML specifications officially allow. This is unfortunate,
but a validator has to do what a validator has to do.

I do this time, but please note in future that this is not normal
practice in public mailing lists. Discussions on this list are
available at http://lists.w3.org/Archives/Public/www-validator/
