That's very interesting since I have exactly the same problem and tried the same solution, with the same results. I'm using the XML Spy schema validator, and I am suspecting a bug in the validator. So I have to confess that I threw the whole schema and wrote it in RELAX NG. It was a breeze. Funny to see how DTD are cool, finally :) So let's be a little bit more constructive. Maybe it could be written using a substitution group or inheritance ? We would have each element such as title, emph, b, i and so on inheriting from the text-model complex type. Have you tried this ? Or better, maybe someone has solved the whole problem !
