Hi, in the last XTM mime type draft, I read: "All XTM 1.0 documents will include a DOCTYPE declaration that begins with ">!DOCTYPE topicMap..." Is this really a requirement? Where do I find it (looked at XTM1.0 but did not see it there)? Thanks, Jan -- Jan Algermissen http://www.topicmapping.com Consultant & Programmer http://www.gooseworks.org
