The devel pages now all validate as strictly conformant xhtml 1.0. I've also run the link checker available from w3.org:
http://dev.w3.org/cvsweb/~checkout~/validator/httpd/cgi-bin/checklink.pl?rev=3.6.2.3&content-type=text/plain (they have an online version but it's very slow) through the pages on www.devel.lyx.org. It took about half an hour to do the whole thing and I'll commit a few of the resulting suggestions. The only page that couldn't be resolved is this in references.php3. Shall I just cull it?
