An XML Schema Declaration for a Sermon

Just something I've been working on for a project (I DO do more than blog, you know). Anyway, the following is code I've developed to try to put together an XML schema defining a sermon. Any ideas?

I know that, theoretically, OSIS could be employed to encode a sermon, but that's not a very satisfying solution. Sermons have elements peculiar to sermons. A good XML representation of a sermon should know the difference between a point and a conclusion.

I only took two preaching classes in seminary, and they were a long time ago. I may very well have missed something important. So if this code is helpful to you, then I'm glad for you to use it so long as you give me credit. And if you can help me make this code better, I welcome the help.
