Mark's last email has prompted something that I've been meaning to ask this list for a while. What are the practical benefits of migrating to schema based EAD from DTD? I know that XML-wise, DTD is the older style and schema is the new, so that schema is the preferred new format. But, I don't think DTD support is going away anytime soon. Are people just trying to achieve the gold standard, or am I missing some other practical benefit. Is a schema easier to work with?
