You can't mix "ANY" with anything else in your content model. (You would use it just like you would use "EMPTY". ) What your current element declaration is saying is: at least one occurrence of: one or more "StoryPara" element(s) followed by one or more "ANY" element(s) Change your element declaration to this: Do note that any child of "Story" must also be defined.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
