That brings me to an idea. I could just convert all named types to abstract elements with a hash sign in front during schema parsing. Furthermore, I could insert "pcdata" nodes in the memory data structure to get rid of the concept of "content type". If I eliminate all the strange concepts during parsing, I do not need to struggle around with them later when doing something "real" with the parsed schema.... > The XML Schema language will soon be moving to Candidate Recommendation > status (we hope).

It's not that it is not possible to use it. But it makes everything more complicated than needed, at least if the API is close to the schema syntax. You always need an extra indirection level in order to access the type information of an element. You also need additional consistency checks for overlapping concepts like content-type vs. type...
