Extending XSL stylesheets to match extended DTD

Hello, I'm trying to work out precisely what would be required in extending the DocBook DTD in order to produce a significant amount of coursework.

As part of this, I want to mark up a curriculum/schedule. This would be comprised largely of block elements, such as the following structure indicates.

schedule

	week*

		lecture*

			title

			presenter?

			topics?

				topic+

					para etc.

			themes?

				theme+

					para etc.

		laboratory*

			title

			marks?

			topics?

				topic+

					para etc.

		tutorial*

			title

			marks?

			readings?

				reading+

					para etc.			(needs work to profile book editions)

I have a rough idea of what I need to do to create a customisation layer for the DTD, but none of the books I've consulted (including Docbook XSL) mention anything (that I could find at least) about the correct way to make a stylesheet extension.

Any tips? Or have I managed to miss something completely obvious?
