[oXygen-user] html validation error

Tue May 12 02:13:31 CDT 2009

Hi Lars,

That should be an SGML DTD, thus the errors when you validate it as an 
XML DTD.
Solutions:

* use a catalog to map that to a local copy and edit the local copy to 
make it a valid XML DTD

* use the XHTML DTD, for example:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
                       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

This is also mapped by oXygen catalogs into a local copy.

Best Regards,
George
