I'm not much more than a beginner myself, but my off-the-cuff approach
would be to make the start-date and end-date attributes of the
<event>, rather than elements. If there's a particular reason you need
them to be elements, then maybe you could do something like
<!ELEMENT date ....
id ID #REQUIRED>
<!ELEMENT event ....
start IDREF #IMPLIED -- or #REQUIRED, if you prefer --
end IDREF #IMPLIED>
Afraid I can't really explain why I like this approach. Undoubtedly,
there are people with more expertise who will give you better answers.
